Since the bleeding stopped, just keep him on clean, soft substrate (like paper towels) and put a little dab of neosporin on it. Tomorrow you can give his little foot a soak in a diluted betadine solution. It should be fine though, when you cut the quick, the bleeding usually flushes out anything really bad, and they don't tend to get infected if it is a clean cut. Just make sure his enclosure is clean so no dirt gets in there while it heals.
