Ok so email all your old customers tell yhem you are now selling here and not on ebay, also anyone you have bought from tell them that if they want to sell to you in future they had better start listing somewhere other than ebay. That would do for starters.
Then blog, plug on forums, stickers in your car, postcards in the newsagents, the possibilities are endless, if we all do that the Ebid name will be in front of everyones eyeballs.
