Photos of Paintings

I'm a painter and need to get photos of my paintings posted on my website. Using a camera or phone to shoot the photos, there can be some bowing out of the edges -- because the shot is too wide-angle. I'm cramped for space (and lighting). If the shot has the 4 edges of the painting almost but not quite parallel with the edges of the photo -- can Photoshop be used to make these small corrections and keep the painting as a perfect rectangle with straight edges ? If so, I'd like to hire someone to makes these adjustments as needed to the photos of the paintings. If not, I will re-think how to shoot the paintings. There are approximately 75 paintings.
