mastering company

There is a company called Massive Mastering. I have seen pictures of their studio, it looks very nice.
Seem to have good deals too. You can send them a disc and they will do it for under $100.
I have never used them but I do intend to try them as soon as I finish getting my studio together.
If you try someone and really like the results. Please put up a post to let us know, who it is you are using to do your masters.
Good luck! :D

nandoph8, you are on the mastering forum, here you will find the top mastering engineers in the world, at least some of them. Check out the websites of the engineers and see who you like, that would be the best way to chose. 8-)
