Print 200 pages translates to 400 to account for printing borrower's copy...so IMO first signing $150-$175+
For the other additional 5 loan packages, no travel as you're already there, I'd say (for me) $100 for each of those - so you're looking at a job worth, IMO, $650 - $$675 total for SIX loan packages. Keeping in mind it depends on where OP is located - if it were me and located in CA, imagine the table time just to document all these into the journal. Fees there would probably be higher.
Six loan packages for $100? I want some of whatever that signing service is smoking.
