Musa is not only fast, but is by far one of the best I have seen on GAF. He is honest, on time, and overall good at what he does and is deadline driven. Thank you Musa, I really appreciate your superb work! Highly recommend A++++

Provider went on a month long trip which I knew about. After the trip, he has not been available to me for questions. I have tried to contact him though GAF, facebook and msn. All of my messages are ignored. Highly disappointed... I had really high hopes in him after the reviews and friendship I thought we had formed.
