Edit an .exe file to remove some software limitations

Hello, I have this very basic freeware and I need someone who can remove two of its limitations from the GUI (threads and maximum number of repetitions, at the moment I can't enter more than 5 and 1000 respectively). I'm no expert programmer, but I think it's enough to cancel/modify a pair of lines of the source code. A bit of reverse engineering is needed. To give you a glimpse of how it's coded, see the screenshot: that's what I see if I open the exe file with Resource Hacker. Bid only if you can do the editing immediatly finishing in no more than 2-3 hours. I'm willing to pay no more than 75 USD for this quick job.
