At this point my "guess" is that the model didn't ask for details or payment in advance because the model decided they already had a video done that they assumed would suit your needs and just decided to say it's done and ask for payment. They probably didn't decide to shoot a custom for you w/o payment.
As far as pricing... $56.00 for a custom seems cheap. $106.00 for an actual custom I think also a very reasonable price. You will likely need to pay more for a custom from someone that has a history of making tickling videos.
