Ok, but, quick question, what quality law firms out there are happily taking on a contact with a client with known issues not paying their contracts?

"Quality" being the explicit delineator?

Surely there aren't many powerful and good law firms who would lie to themselves and say, "Yeah, sure, Elon's not paying his bills, but whether or not I get him off the hook this time, he'll definitely pay me because otherwise I'll sue him, too?"
