Find buyers for websites

There are 4 good sites (not voreznik) with a attendance of 7,000 uniques per day each. The profit on each of them is more than $300 per month and is only growing. Costs – about $100/month for maintaining positions, hosting and domain. I’m willing to give $500 from each site, provided that you can sell the site for $5,000 each. Each website will pay off in 1.5 years at most! I am selling because I need money right now. I'm looking forward to the answers!
