Background: Deal attorney, used to work on big/middle market deals, now focus on sub $5M

Question: I have a lot of clients wanting to treat their sub $5M deals like the mid market or larger market deals. Sometimes they came from M&A at a big company or otherwise have that traditional larger viewpoint. Some of the things they expect are quite different (very rarely have stock purchases, diligence is very thorough, reps in the APA and indemnity are hotly negotiated) in the smaller space. Part of the reason for this (I am guessing) is that no one gets R&W insurance at this level. That alone changes the negotiation ecosystem considerably.

Does anyone offer this insurance for sub-$5M deals? Has anyone explored it? I am assuming it's crazy expensive relative to deal size, but I don't like assuming.
