Congratulations on being on solid financial footing. I think your blanket characterization of lawyers is a bit unfair. And even if they were “crooks,” remember that if you’re the one retaining their services and paying for them, they’ll be “your” crooks (you’re the boss!).
I’d be wary of government or non-profit help: do you think the best and brightest would be working there? I don’t think so. If government entities were the solution to all problems, Cuba would be a super power.
You got some excellent advice on this thread. You may also inquire at your bank; since you probably have sizeable accounts, they’ll be glad to spend some one-on-one time with you. If you have a fee-only financial advisor, he/she may be able to refer you to a competent lawyer as well.
