Anyone that can help!!!

I've tried using the C# and other express editions put out by microsoft to look at this module.  I'm a novice computer programmer at best and haven't been able to make head or tails out of this module.  What I would like to do is change the tax portion so that instead of doing it for everyone or no one, that it would be able to do taxes for only a single state.  Is there someone who can help me?  I'm sure there must be many others that would benefit from that, but I can't figure out how to do it on my own.  Any help would be appreciated!!

OK,

Well I haven't done any real programming since high school and that was c+ on a unix box.  Unfortunatly this seems very confusing trying to work on it from express programs.  Could someone recommend someone that I could hire to make the changes?  I need one change, I'm sure it would take a couple of hours if you know what your doing....  For me I think it will take days, if I can figure it out at all.  I'd like to try and fix this module as I've entered about 75 products into the store and don't want to lose all that work.    How much would it cost me to get the store to have a tax rate for AZ but no one else?  Is there a different forum I should be asking this in?
