Need help mastering a few songs!

[JuanFerVal]

Don't know if this is the right forum to post this... anyway, here it goes: my name is Juan Valencia, and I live in Quito, Ecuador. Been a long time PT user also. My first PT system was a Project, then a 001 and now I own a 002. I recently upgraded to a MacPro Quad after many, many years with a first generation G4. So I finally have the horsepower to do a record with my band, a long time dream of mine. The thing is now I need to master 3 songs to send them to the radio stations here to get some airplay (the music business is very different here than it is in the States), but we're very short on cash. As you can imagine the cost of living here is also very different here than in the States. I'm looking for someone to lend me hand in mastering these songs without charging me too much for the job.
If anyone of you guys can help me, thanks a lot!!!!
Best regards to all.
