Most escorts that offer full service do not post a BBBJ only rate. It's possible some might do it, but personally I would think twice. Any full service provider who does well will not want to give up their time for less. So, you may be getting one that doesn't do well, and there likely is a reason for it.

 
That said, there are some that offer massages with a BBBJ finish. These are providers who do not offer full service. And, the BBBJ finish for them is their high end rate, but usually cheaper then getting a provider who offers full service. I suggest looking into those who advertise massages, and see if any include a BBBJ finish.

 
As for filming, that is going to balloon the price. Not many allow it. And, if they do, it usually jacks up the price. I don't see how getting filming included and the word "Affordable" will work together in your favor.

Wants face to be covered so filming a BJ is not going to work well.  I suggest reaching out to a few girls you like and see what they say.
