Thanks for the feedback - I'm going to see how much it will be to paint the floor. If it's going to cost $$$ I may opt not to.
For those that might be interested I had a Certified Mobile professional welder come to my garage and replace the pans along with some other rusted areas in the rockers. I liked the fact that I could see the work being done vs. taking into a body shop. Total cost was around $4,200.
