Added to that, if you mean can you earning a living providing that service alone, I think it might be difficult for someone who also offers full service to ascertain that. I think it's like the outcall thing. Most guys tend to opt for full service incalls if they are available, but I'm sure that some of the guys who generally go for full service might also pay for hand relief (that's what it boils down to) if that's what you offer. Some NEED full intercourse as a part of the 'deal' but I'm sure if that wasn't offered and the price was reasonable many would also try those who offer hand relief only.
Maybe see if you can find someone else in your area just offering this service and see what they charge for it. As for hotels; you could use them in much the same way as full service escorts use them but I always think - as with touring - to only pay for hotels and so forth, especially in a new area, if you have the funds 'to spare' and you can risk it going either way.
