one song mixed and mastered

I have a demo, I have always mixed everything myself but I've always wondered what I would sound like if it was done by a professional such as yourself. I'm looking to get signed one day and have realized if I really want this I need to put the money into it. If we end up working together and I like the way it goes id love to hire you in the future as well. Below is my song "Paper Boats", This is the demo i would like you to mix and master

Additional info:
I need the mixer to do some editing, time aligning and vocal tuning before mixing. I don't have a hard deadline for this. The song is fully recorded. I just need mixing and mastering.. Check out the song I attached. I'm an indie artist. I'm interested in working with a very experienced mixer. I'll need you to master it too if possible.
