I think it is something that will vary greatly from provider to provider since many aren't even willing to do it at all.

The only time I did it it was $50 for a POV session where I held cam the whole time.  I think she charged $150 to have a friend come and video the session.  But like I said, I don't think there is a standard.

Was the footage good?  If so, then whatever you payed was probably worth it.

Also, Could you let us know who the provider is?  Its always nice to know who is offering this service no matter the cost.

Thanks.
