Website setup with Amazon Intergration

I need a custom website setup using my Amazon FBA inventory. It needs to have a shopping cart setup and be able to import Amazon FBA inventory to display on my website. Syncing of inventory levels would be preferred, but not necessarily required. AN out of stock for items with 0 inventory would be a nice option.

I'm open to 3rd party intergration but do not want to have a high monthly expense as this will be mostly to gain wholesale accounts and not so much to have actual sales. I'd like to be able to select the products I want shown as currently I have 2,500 products, but would like maybe 250-500 in the storefront.

I have already secured the domains and have a current Amazon FBA account.

Please respond with past experience and with your proposal for 3rd party intergration with the expected monthly cost. I will be supplying images and logos for the landing page as the project goes on.
