Create .ipa file for an ipad app

Hi, I had one ipad application created earlier this year from a professional here, I have all the source code, and the app works perfectly in the ipad simulator on xcode and when testing on the ipad plugged into my computer. The issue is i need a .ipa for a list of UDID's and i need someone to create it for me as soon as possible. I've read loads of tutorials on the internet, and it seems like it's an easy thing to produce, but since i don't have a Mac right now it's a little difficult for me. So I'd like someone to do it for me please. It should only take a freelancer 5-10 minutes This should be something fast since it's a simple task.
