I think what you are asking is how can you specify your auctions as free and paying listing fees on fixed price over the 250 limit. There is no way to do that. You get 250 free listings a month and they are used in the order of items being listed.
With the number of listings you have, it might be time to consider an eBay store subscription.
ALWAYS be honest and exceedingly FAIR!
