What advice would you give a customer looking to hire a provider in your area of work?
I would suggest that the customer look at the web sites of other people/companies in their field or that offer the kinds of services he/she/they are offering. Then, make a note on what you like or don't like. This gives the customer something to bring to the table and it saves a lot of time and money. It's like looking at other people's houses before you build your own.
