As much as I'd love to say I could help you Kimberly, it's above my head and I'm sure many other's heads here too. What you're asking people to do here is give you support for another site's software and that's pretty much above what should be expected here.
Having said that, there are a lot of different tutorials, even free classes or cheap classes on PHP if you want to learn it and you can also go to Fe Pixie's site and see if anything there can help you as she has a pretty good help site for PHP at
http://www.pixieplots.co.nz/forum/viewforum.php?f=4 for lots of different PHP and other website stuff. I would suggest you look around for some place to learn about PHP and see if you can get the hang of it yourself, or... if you're looking to hire someone here on the forums to help that would be another way to do it, there may be people on the forums here willing to take time to teach you for a fee.
Anyways, I think you should take a look at what it is you're wanting to do and then go from there. If you're looking to hire someone I would say make another post in this section of the forums or in the breakroom with the title stating what you're wanting to do so people know you're searching to hire for help.
Wish I had more suggestions or resources for you, but Pixie's is bout all I have onhand on this computer. Others may have some suggestions for where you can learn more on PHP too. In the end though, I don't think asking people here to support someone else's software is a good thing to do. Personally I wouldn't use that software if the people creating it aren't prepared to support it. That's just me, but if I'm going to use something, the people making it had damned well better be prepared for questions and problems, or be prepared to go out of business pretty quick. If they are that swamped they shouldn't be taking out the problems on their customers, they should be hiring more help. They are obviously selling their product if they have that many support tickets, so hire someone to help with them and give your customers the support they deserve.
Good luck on it
