Mastering/mixing needed for 6/7 track album

Hi, I am currently writing my debut album and I need help with mastering/mixing and in general producing the album. I have finished almost all of the songs, however I don't know how to get the songs from ideas to actual professional sounding songs. The theme/genre I am going for is something I've never heard of before. Pretend you're combining Muse and Pink Floyd, then take a neoclassical version of that. I actively play electric guitar, however I write compositions on piano.
