Heeelp, need advice on mortgage

[TheArtist]

Two years ago this month I bought my first home.  As an artist and at the time not having the best tax records I opted to get a mortgage where they didnt "look" at tax records.  It had a provision stating the first 2 years were locked in at 7.85% but after the first 2 years they could start raising the interest every 6 months.  

 Guess what I got in the mail today?  My first notice of the new interest rate.  Its now up to 10.85%.  The old monthly payment was 828$ the new payment is 1,065$.  And they will probably raise the interest rate again after this 6th month period.  ICK!

 I now have all my tax records up to date and have never been late on a payment.  Any advice on where to go to refinance my mortgage? I got my mortgage from  EMC through Mc Graw Davisson. I am not very good with understanding finances and numbers so need someone I can trust.  Any advice would be helpful.
