Unfortunately, there were too many new sellers offering high value items and not delivering on their promises. The result is that eBay now has restrictions on new sellers which can last up to a year.
Your best bet, as a business, is to keep your eBay account, but to spread out to Craigslist, Kijiji and specialty sites to get the sales your bank account needs.
As time wears on, the sales on other sites will teach you more about selling and shipping (and about buyers). By the time eBay is willing to give you more trust you will be an experienced seller.
You may even find a site that works even better for you than this one.
