Do you have a Lawyer Referal Service in your area? Often they will connect you with a lawyer for only $20 for the first appointment. One appointment may not complete what you need, but they will be able to point you in the correct direction.
You might also consider posting your question in your geographic area in MDC's Finding Your Tribe forum, since laws would be specific to your state.
Sounds like some serious business. I hope it turns out well.
