Will it change anything if you just let it saved and not published at first?
Great color combination, but it has a lot of spaces that are not used. Overall, it looks great.
I suggest for you to go to any freelancing site like odesk.com. I am sure you will get plenty of available workers from there.
That will depend on you how your site to be shown online, but for working on themes, that is a different story. You have to work on the right specifications.
Your site looks great already, but being unique when it comes to design and other feature will make your theme being approved.
You can always check a lot of good contractors via freelancing sites. I always get my help from their.
If this position is still open. I am happy to work with you and help you on it.
Actually, any template will do. Usually, the more technical the theme you choose, the better and quicker for you to learn.
