Unless you hire someone who is a close personal friend , I doubt you will find a credible pro photographer who will do what you request at any reasonable cost. This is just not how the industry works.

The Captain is right. I know of no professional that would provide his/her raw files without specific limitations and a hefty fee.

What you are describing is an issue with dynamic range. You should shoot interiors with a tripod, significant DOF (f/16, f/22), use multiple exposures, open the exposures as layers in PS, and blend them into one image.

Catchlights bring attention to the eyes--one of the purposes of portraiture. They should be present to bring life to the eyes--but only one per eye. Often, one has to remove other catchlights from sources such as fill lights, etc.

You should budget at least what you would expect to pay for a good lens as a starting point for your tripod and ballhead. In my opinion, the two most important items to purchase after a camera and lens is a GOOD tripod and ballhead and an off-camera flash. A good tripod will last your shooting career; a poor one is wasted money.

Remember WIMPBE--Before shooting, check White Balance, ISO, Metering, Program mode, Bracketing, Exposure Compensation.
