Hire a lawyer of your own!
I know folks have questions and worry about paying a lot of money to a lawyer when we J.D.s at the SDMB have all the answers, but please, you need to hire your own lawyer.
As others have pointed out, we probably aren’t allowed to practice where you live, so it would be unethical to give you advice.
Also, we can’t give advice because there is no reasonable way to make sure that we don’t have a conflict of interest (remote as the possibility may be).
Don’t get insulted, but laypeople don’t always understand enough to fully describe the problem - lawyers need access to your books & records, and we need to be able to call you up and ask questions periodically.
Anyway, you can probably get decent representation (at least an idea of where you need to go) for a few hundred dollars. Generally, lawyers don’t charge right from the get-go, so you should be able to call up for a brief phone consultation without charge. Try to get a young associate to do the bulk of the work on your case, if possible - you’ll get a lower rate, but the associate has the support of more experienced lawyers, so you’ll still get good representation.
Depending on your situation, pro bono lawyers or clinic lawyers might be available - do a little investigating. For instance, my law school offered free tax advice every year.
Finally, pro se is a bad idea. Pro se defendants are eminently annoying to all legal professionals, who are used to a (relatively) smooth-running system and a certain detachment from the emotional issues of a case. As others have pointed out, even if you are the best pro se defendant ever, you are liable to get upset, not know procedures, and generally throw a monkey wrench into the process which irritates everyone, including the judge.
I mean all this with respect - the most intelligent people can be stymied by the legal system, and even lawyers who get personally involved in suits hire lawyers to represent them.
