I have years of experience using lightroom, which will get the photos looking sharp and in tip top shape, but you need more then that. I also have extensive photoshop experience and will easily be able to get rid of the background, add in something different, whatever you want done, I can do.
Plan:
1. Start off in lightroom to do basic retouches, changing white balance, adding contrast etc.
2. Then move to photoshop to change the background, remove and unwated glare or artifacts.
3. Keep in contact with you and return the photos in a timely manner!
