There are two pages to the Sell Your Item form.
Did you click on the List My Item button which appears below the fee you will be charged if it sells?
Did you realize that it can take up to 24 hours for a new listing to "index" and appear on eBay?
There are restrictions on high-value items sold by newbies. This may be part of the problem.
Have you worked out how you will be shipping the set? If you are only offering local pick up for cash, it would make a lot of sense to use Craigslist or Kijiji, which are free rather than paying eBay.
