EB*ay sni*per problem

Hello First of all, I would like to get someone who understands English very well, someone here in the US preferably if your rate is not too high. It's hard enough to describe the problem to a native English speaker I think, let alone someone whose English is not the best. I have an eB*ay snip*ing website that is having some trouble sometimes with logging in to eB*ay and getting through the bidding steps. The majority of snipes are okay. The ones with the trouble are sprinkled in with the ones that execute fine. We have a main server and then a mirror server both submitting the snipes and when one server has trouble with a snipe, the other server normally executes it okay. At first my programmer thought that it was SSL related because we were using HTPPS to connect to HTPP, but he changed to HTPP, and we are still having issues. Now I think he thinks it is a curl issue, but he really doesn't know what the problem is. Apparently it is difficult to figure out. I don't know what you would call the type of programmer I need, a debugger, tracer, whatever. You must be good at figuring out difficult issues. I can make a video to show more about the issue for whoever works on this. I may add to this description after chatting with the programmer again. Thanks
