If you are talking about somebody taking physical possession of the items and using their account to list and sell the items as well as handling all the logistics, returns, buyer issues and tax liability that may be difficult. Even if you do they are probably going to want a significant 50%+ percent of the eBay net profit to cover taxes and risk.
There have been a lot of posts like yours looking for consignors. I assume some of those are to potentially avoid the tax issues and the receipt of a 1099-K from eBay. You need to realize that the person you consign to would be required to issue you a 1099-K for any profits they disbursed to you so they are able to write that off of their own taxes.
If you are looking for somebody to simply use your account to list the items and you handle the logistics then caldreamer suggestion of finding a teenager to do that for you is probably the best avenue. If you are simply looking to unload a bunch of stuff and a quick turnaround you might try a local auction house or list everything as one big lot on a local forum.
