Multi Channel Fulfillment Setup and Maintenance

I need someone to get me set up on a good multi channel fulfillment site. I have accounts with Amazon, Walmart, eBay, Bigcommerce, etc. I need someone who has experience with using a multi channel fulfillment platform and getting everything in sync (listings and inventory). This will begin with setting me up on a quality multichannel fulfillment platform like ecom dash. I want to expand our bigcommerce store as well and set it up to be a daily deal offering site. I want to get set up on getting all my store listings and inventory in sync. This will lead to consistent work. Please message me with any questions or proposals. The pay will work as the following: - Set us up on all platforms with the multi channel program, get all our listings on all platforms, and inventory synced - After the first project is done, we will switch to hourly work
