Don’t worry about having too many people contact you all at once, or having everything perfect before you start contacting people. Once people know that there’s someone out there that they know and can trust to sell off their things on Ebay, you will get responses. Encourage them to pass the email along to their friends and family. Offering a referral bonus can always help get some new business, too (and it still won’t cost you anything). Delaying this crucial step will do nothing but hurt you!
