What can I do in photoshop to these photos?

Sarah, please don't take this personally, I offer it as feedback. Those pictures are kind of boring, Sorry. I don't see any thing that would want me to chose this studio over another. They have a large mixing board there but its the secondary subject in the photo, your lens is centered on the technicians. Can you get some temp lighting on it for some more pics? Maybe a couple of panoramic shots of the recording room its self with a large display of their equipment that would be available to the customer. That would be more impressive and enticing. Good luck with the project.
