Create 250 "professional" look ebay listings

I need to have 250 listings with a "very professional looking" (gadgets) I will provide links from where to get description and pictures (I need them without the original picture label) and insert mine. Also templates need to get upload at a server or whatever it is recommended (I don’t want to pay for storage service for my templates, if it is merely code much better) That’s all I need, I will take care of the rest (upload them to my eBay) I don’t care about format or colors, as long as it looks clean, attracting to customers and professional. Requirements: I need samples of previous works (eBay listings)
