When I lived in California, I had a great rep in LA a few years
back. She did most marts and on road sales. You need to get hard
copy confirmations. Jacqui Moss kept me busy and allowed me to
stay in my studio to work. Eventually, I got out to New Mexico,
Arizona and LA to meet some of my clients. For me it was great.
However, I was introduced to this agent my another artist who
was being handled by her. Word of mouth....who you know and all
that is often the best way to find the honest ones. Make sure the
agent "invoices" the work to you and there should be no trouble
as long as you are able to support the agent by getting the work
to the client on time.
