Gear bubble mug designs and Amazon intergration

Hello, I need someone who is familiar with gear bubble ( the on print demand website) to design multiple designs for mugs and to upload with the amazon integration software which Ive upgraded for, onto my amazon seller page with enhanced key words etc. Ideally I would like 10-15 designs uploaded a day onto the gear bubble site and then onto amazon. Someone who has had experience doing this would be preferable.
