I'm lucky because my partner is normally my helper, and he is pretty good. But it took me years to train him to be better with people, as he is not a natural salesperson or a "people person".
I have had various helpers over the years, some family, some friends and acquaintances, some strangers (recommended by people I knew). Some of these were good and others were practically useless. Most of the time I paid minimum wage, sometimes a piece of free jewellery thrown in there, feed them while at the show, gas money (for one show that was 1.5 hours away).
It can be hard to get a good helper, especially if you can't offer regular employment. People are busy with jobs, kids, etc. An older person may be a good choice, because they have more free time and be interested in working just for the novelty. Once I had an older nurse work for me, she liked being a salesperson as a break from her stressful job in a cancer ward, and she already had experience from working in a gift store. A younger person might work out because they may not be weighed down by responsibilities, be more flexible, and happy to work for cash.
Also it depends on what kind of helper you are looking for:
- someone to help you load in and set up and tear down ? Watch your goods while you park? These kinds of helpers are often easier to get.
- someone who will watch your goods, to prevent theft (always important when it comes to jewellery)? Be there basically so you can have short breaks?
- Someone who can handle money (do math), wrap up sales, put out stock?
- a good sales person, someone who at least can be friendly and outgoing?
Last summer we have two overlapping events. For both of these we knew we would need helpers, as it could get really busy. So we ended up with:
A) For the outdoor event my sister's boyfriend came out for 1 1/2 days.
This show required the entire tent and display to be set up and torn down every day. He was a great help with the "schlepping", but could barely watch the jewellery (was always on his phone), or say hi to people even though he is a naturally friendly person. It wasn't as busy as expected, but his being there meant I could go to the bathroom, get food, and have help with the physical labour. Because he has a well paying professional job, he didn't expect to be paid, so we gave him a gift as a thank you.
B) I BEGGED a friend who has helped me over the years to come out for the second half of a day (a full long day in the heat was too much to ask). She has small children so it was a favour even though I paid her (and gave her $20 for gas). She is a little bit shy, but smart, learns quickly, and pays attention. Even though she normally helps me only once every year or two she remembers what to do, and what to say to customers. By the time she arrived, I was in a heat haze and it had started to get busy. That I could sit down and let her run the booth for a bit was a great relief. If I could only afford to give her more work, I would.
C) The third person helped me at the indoor event. She has helped a friend of mine at many shows, and kept offering to help me.
She practically works for free, likes to have jewellery in exchange because she is on disability. It wasn't as busy as expected, but she wasn't the kind of worker I was looking for. She kept taking off without asking first, because she wanted to look in on a nearby performance. When talking to customers, she would tend to ramble on a bit too much, wanting to tell them all about herself and the things she liked. Her sales/personal skills were better than A, and she liked being at the event, but I would only use her in the future if I was desperate.
Anyways, I know crafters who have managed to find decent temporary help just by placing an online ad. I think if you can find a good candidate, train them and use them a few times a year, it's a good investment. Don't expect to find "gold" right away, and it's likely that no one will ever be as good as you, when it comes to selling your craft.
Also, maybe you don't need someone to be with you for the full day, just the peak hours - like 11-4?
