Magento and ecommerce assistance

My business partner and I are American and we're starting a Magento based e-commerce company. We need someone who's familiar with Magento to:

*connect our domain name to our Amazon Web Services account (we are set up on both sites already and can share the log in info).
*install an existing script we already purchased from this website: Upgrade to see actual info We have most of our content ready!
*make edits we request (uploading company logos, changing company information, all the basic things that need to be done to customize the script template we purchased)
*assist with getting payment gateway installed on our webpage - we have a merchant account with Amazon Pay.

In summary, you would be our developer contact with Amazon Web Services (AWS).

For the moment, this wouldn't be a full time job as we are just getting started. Can you kindly tell us if this is of interest and your hourly rate? Thanks very much.
