Well I feel like a doofus...

Well got a return voice mail from attorney 2, who already has some nurses he works with and is happy with. (Of course he does, he's a successful medmal attorney!) Of course, already have a follow up letter in the mail to him. So I think my plan is to send an email thanking him for the return call, and to keep me in mind if needs something when they're busy or in my specialty. That way I don't waste his time bothering him with a phone call, but I do get to follow up rather quickly.
So, I've successfully made contacts, have not successfully gotten a client yet. Will focus on the fact that I sent awesome letters (thanks sirI for the help!) and did do my follow up, will improve on the phone calls though. Now to find a couple more prospects to start anew with...
