Hi,
it really depends on at whose party you are performing, and how others around you charge.
If you live in a city where heaps of ladies are ready to spend their evening at someones party for some pocket money and a warm meal reading tarot cards till their voices say goodbye....ohoh... ;-)
If you work at someones elegant party you can charge considerably more. Also the time you work makes a big difference. Some ladies work 2 to 3 times 40 minutes per evening, others up to 6 hours with very few breaks in between.
The prices people charge seem to be very different, and I know of people charging between 50 Eur and 2500 Eur per evening.
I myself am a fan of getting paid by the hostess completely, as this always comes down to a higher fee per evening. Although: If you are just starting out you need to go the lower income route of being paid by the guests sometimes...
As far as I experienced charging only 2 Eur per minute can mean you drive somewhere, are there x ours before the event, and can only take your decoration down at 3 in the morning when everything gets quiet... Then you drive home and find out that you invested 15 hours or more of your time for 150 - 180 Eur.....
And if the place of the event is a little farther away you will also not have one client turning up at your house for private readings, as people are to lazy to drive...
Not cool.
So I always tried to make sure that if I invest x hours of time for a party, that I got paid a decent amount. That usually means that the hostess had to pay for the cost of my decoration, the cost of driving there, the time I waited at the event before and till I could take down my decoration etc. I also found it is easier to sell short readings of 7 - 10 minutes for 25 to 30 Eur to the guests, then to go the 2 min per hour route, or the 3 Eur per min route.
Some other pitfalls I stumbled into when following this model of work:
Beware of people that want to talk to you 15 min without paying you, about tarot, the way you work, where you learned this and so on...Then they want to buy a 10 $ 5 min reading. They next have questions that take 12 minutes. Still they would like to pay only 10 $, as that was what they asked for in the first place: A 10 $ reading. If you took soooo long to answer their questions it is not their fault, but yours, they say. Grrrr..
(So really always make sure you charge by the minute if you do, and that longer readings need to be paid.)
Beware of hostesses that "know" so many friends at their parties will want a reading...
that tell you they will have sooooo many guests attending their event, where you find out after driving there over 37 the hills and valleys, that only 12 people attend the event. And that only 4 of them want a reading, because the thers are absolutely opposed against psychics...And the 4 that want a reading think they want to pay a max of 20 Eur, for a 30 minute reading, - because that is what the local tarot reader is charging too... ;-)
If at all costs you have to try that way of working, make the hostess handle selling x readings for x amount of dollars as a minimum. Make sure that is the min she needs to get together, and that a "oh, I wanted to sell 6 redings, but 3 of my friends that said they would buy a reading did not show up" will not be acceptable. (She then needs to bridge the financial gap.)
Also try to make a friend of the hostess handle the appointments, if you do short back to back readings, as you could loose to much time answering unpaid questions about tarot, psychics, your experience etc.
An antidote about those heaps of questions from to many people is if you introduce yourself in a short 5 min talk, hand out some info flyer about you and how you work, + have a collage of press articles put into a large photo frame for people to read. (Put the articles behind glass, otherwise oily fingers will make them unusable after a few parties ;-)
However: I feel it is much less of a hassle to just charge the hostess, and offer free readings to the guests
Nowadays I do not do those party readings any more where I have to chase the guests to get paid doing readings, as the risk of earning much to little is to high going that road.
If you like to sell readings per minute, how about doing renfaires?
There you set your tent up one time, and have time from thursday or friday to sunday night to sell readings, not just measly 2 and a half hours, like it is with some parties, minus the unpaid time of handling pretalk, enquiries etc.
So ohoh...I really am no fan of the "chase my guests to be paid" model ;-)
Instead get the person that organizes the event to pay you, and all is well.
And think of 500 Eur + cost of driving, hotel + vat and up as a minimum, if you need to live from that line of work.
If your references do not allow that, try to get at least 300 Eur + what the guests pay you.
