Amazing eBay seller with perfect account looking for Supplier.

I'm posting this with the minimum project budget since we all know you will receive a cut of the profits from each ebay sale. (that's where your money comes from) I've been selling on eBay for 14 years off and on. The past few months I've started to sell for other people (Suppliers/Wholesalers). I've been burned by 9 out of 10 suppliers. I thought I found a great supplier who I've been with for a couple months now but they are completely unreliable and take days (up to a week) to respond to me. I've been on of the top sellers of Pebble Smartwatches for a while so I'd like to find a trustworthy supplier of those smartwatches if possible. I'm open to alternate items to sell instead though.. I have been told I create amazing listings (I put hours into each new listing design). I have excellent customer service (respond within an hr or two always to everyone). I almost always get a positive feedback after each sale I complete. Please let me know.
