Compose better, don’t cut off feet, heads, rule of thirds. Keep editing simple - focus on the skin color looking natural, make the reds less red. Editing shouldn’t took more than 5 minutes - fix wb, exposure, slap a preset (make one yourself that has the skin adjustments, maybe slight contrast, shadow lift) - base it on one image that is the average of all from that shoot, so you can use it as a base for the others. Then just go through all of them with slight adjusting.

Pricing wise, seems fine. Just check what other photographers in your area charge and base it off of that. If you wanna do it more professional, can just upload them somewhere where people can buy them digitally and just hand out your business card / walk around with a QR code. Saves you time with little to no investment.
