It sounds like you're trying too hard to sell this case to some unsuspecting young lawyer who you want to take it on a contingency only. Most knowledgeable lawyers know better. Sorry. Nothing today is simple and easy and this case certainly isn't an easy or simple one. And, at most, you're talking about an attorney working for perhaps months or more to collect a portion of $7000. at risk. What happens if the company goes bankrupt? Then what? I honestly don't think you're being fair here. I've answered over three thousand questions and never said that before on this site, but in your case, I'll make an exception.
Why not be honest and tell us you have a difficult case that has to be completed before you can afford an attorney and you need help. Maybe then someone will lend a hand.
Good luck nonetheless.
