Google Apps Problem

I have a problem with my google aps account and am getting a fatal error message when trying to send or receive emails. All was working well and then it just stopped. I route all my mail through google apps and then POP3 it to outlook. I need someone that understands google apps and its set up to trouble shot and fix this problem. Something may have happen to CNAME but I don't really know. Only if you really understand Google Apps to bother applying. In saying this I am also looking to have someone on hand that can trouble shot and do other jobs in the future. I'm not looking at paying more than $20 for this
