What’s the best method to sell a large quantity of graded and raw RC’s?

What is the best method to sell 300 PSA graded rookie cards 1980’s-present ($5-$35 range), 400 raw rookie cards ($3-$10 range) and about 75 boxes of wax. I am looking to slim down my collection to about 100 key rookie cards and a few higher end boxes of wax; while selling the rest. I have had poor results using the eBay auction format in the past. I always seem to get the bottom end of the average sales price. I am not in a hurry to unload it and I would rather be patient and get the best price. I was thinking about using BIN’s or setting up an eBay store. I realize that the fees will add up quickly and I was wondering what would be the most cost effective.

Ditto.
Or setup an eBay store.
I would start with an EBAY store.
Use high BINs, be reasonably patient, adjust prices as time passes.
