I prefer files are sent as WAVs labled properly, if they aren't I will send money or you have the option of paying extra for me to organize and name the files. I mix in Presonus Studio One version 3. I also own serveral plug in bundles. After mix is done I allow for several revisions after initial listen through. If by chance you need to do overdubs, I can add those to mix but that will be an extra fee.
I use Studio One version 3 to master, I can add ISRC/EAN to files and Meta Data, such as Comments, Songwriter, Composer, Arranger, Genre,Year and Artwork. I can deliver files as a Digital Release as .mp3, .wav, .FLAC, .CAF, .AIFF,. Ogg Vorbis files. I'm also able to deliver as and Image or DDP file. My turn around is usually a couple of days.
