where is the best place to sell an Amazon Affiliate website?

I own an Amazon affiliate web site that sells jewellery and has links to other Amazon products
I have recently bought another Jewellery site and have six affiliate websites all powered by Amazon and make a nice income on sales which Amazon pay 5% which can raise to 10%
It cost £5 hosting the only running cost of the site and the new owner would also own the domain outright
The site is listed in Google and I am looking to sell the site and am inviting offers but wonder if anyone has any ideas where to advertise the site
