Hey. I live in Boston right now, and I've seen a few ladies here. I only see independents though, and they tend to be on the pricier side $600-800/hr. You can thank FOSTA for that. I wouldn't risk anything lower, personally.
You can use Eros or Slixa, and Twitter is helpful.
If you're still interested, send me a DM and I can give you some names.
