PHP pro

Hello We have a website (a clip share type site with packages) we also host profile pages like MySpace but you have the ability to post them in different areas example new york or Philadelphia usa or canada but we have a problem our free mode doesn't work (very important our site is live so there can be no mistakes must be a expert) ***What we need is someone that can quickly look at the script and fix the free mode...so our user can use all the features of the site then when we don't want it to be free anymore we can switch it to package mode
