eBay and PayPal fees are not nearly as much as rent and utilities on a another location. Hire a trusted friend and pay them a percentage of the profit (20-25%) on each eBay sale. They do the photo's, listing and shipping and you retain control. The trick to eBay is doing your homework. Research the sold prices and the quantity sold versus the completed listing to determine if an item is even worth listing. Current listings are worthless because anyone can something for what ever they want but that doesn't mean it will sell.
The listing title is the most important. when researching an item, try running svseral searches worded differently to see which one returns the most items, then use it as a model for yours. eBay isn't difficult if you take time to figure out what works best, and by all means use good grammar and correct spelling.
Lastly, you can even link your eBay store to your online store page so you don't have to list twice.
Hope this helps.
