Have a mac with xCode ?

Got a xcode ? I have a apple developer license, i got *.mobileprovision *.cer or i can allow you to login to my developer at [login to view URL] and you take what you need. so basically I need to setup build my apps with phonegap. as says here - [login to view URL] You import my certs/mobileprovision and export *.p12. I don't have a mac and i cannot do this myself. I'm using phongap to compile it, but i need to find someone to set it up. Thanks.
