Thank you for your question. I am one of the attorney experts here. Michelle properly stated the rules we have to abide by, which are also based on the laws of all of the states, which prevent us from representing anyone from this site or from making personal referrals to our colleagues.
As far as getting your case out there en masse to attorneys in your state, there is really no other way to do this other than by mass email to attorneys in your area. The sites used by other attorneys are http://www.martindale.com or http://www.lexmundi.com or http://www.hg.org to locate attorneys in your area and send them emails about your case.
Alternatively, there is a site called http://www.legalmatch.com, which is a site that allows you to post your case and attorneys who are members who might be interested can see it and choose to contact you. I cannot vouch for how good that site is in getting responses, but it is another resource for you.
As far as contingency fee cases, most cases contrary to popular belief are not taken on a contingency. The main cases taken on a contingency are cases involving personal injury claims where the attorneys can be reasonably assured their client will get paid for pain and suffering damages. Cases involving things like breach of contract
where only actual damages can be awarded are not usually taken on contingency fees because they most times do not yield enough for the attorney to recover his expenses, much less payment for their time and services.
I am sorry, I hope this helps point you in the right direction.
