5 Songs Editing/Production

I'm looking to write an EP album (about 5 tracks) - so far, I have loosely written lyrics as well as preliminary beats/ideas for each song. The music was made in Reason, and it doesn't have the depth I would like it to have. I'm looking for somebody to take these pretty basic ideas and create backing tracks for me to sing on top of, and to edit my lyrics to better flow with the music. The lyrics are for vocal lines as well as some rap parts. Please let me know what the pricing for this project looks like, as well as what the process would entail. Thanks! I've attached an example that shows the basic quality of the type of beats I've made so you have a loose idea of what there will be to work with.

Additional info:
I have lyrics written but need music and a vocal melody. I need the mixer to do some editing, time aligning and vocal tuning before mixing. I'll need you to master it too if possible. Check out the song I attached. I'm interested in working with a very experienced mixer. I don't have a hard deadline for this.
