What is your advice for OP in how to find those prospects? This is a thread with that goal in mind, do you have any advice for him on how to find prospective clients?
Yes I answered in other comments in this thread. I have a couple of long articles about finding freelance work, how to work with freelancers, and maintenance programming as a career on my web site typicalprogrammer.com, which I mentioned in my reply to OP.
