The service I am offering is to make the best sounding product for any desired platform. Including R128, genre specific mastering and E.P. or album mastering. Every song may need a slightly different approach but I am using the same basic starting points to accomplish the sound you want. I don’t use hardware to master tracks, I solely use software such as:
Black Box Analog Design HG-2
Shadowhills Mastering Compressor
NOTE: Mastering is a special and delicate task executed by experienced professionals.
I recommend looking for a mastering engineer that has a lot of experience in your genre for the best results.
