If he does go to court with a lawyer the costs will be a lot more than $800, but he can sue for legal fees as well as the loss. If Meta is being unreasonable enough that it has to go to court he will get those fees. A judge will not like seeing this trivial cost go to trail, if it gets that far the judge will be looking to see who is not reasonable and slapping them with as many fees and costs as he can.
For a lot of small-claims style things, lawyers will give you 15-30 minute consultations for free (YMMV on how useful these are, by nature its often the lawyer giving you a bunch of information you may already have, will only a couple of minutes for actual questions that they may not be ready to answer), even if you don't have a preexisting relationship.
I've seen this a lot in tenancy cases, where basically they filter out "bad landlord withholding rent" small claims style cases from "bad landlord doing illegal renovations or owner-move in evictions" that can be larger and more complicated, and want you to hire them for the second, but will give you some time for the first, in hopes that you remember that help when you run into the second case.
Not all small businesses have lawyers. I would guess 90%+ don't need them and the other 90% cannot afford them. I've founded and operated a small business for 9 years and have only hired a lawyer 1 time for contractual negotiation. For what it's worth I am in a heavily regulated industry and I have no legal background.
