Most (read ALL) owners overvalue their business. Get an honest valuation from a broker and let them use their channels to help with the sale as well.
While you could do it on your own, it may acutually drive the price down.
maybe explore options for a partnership? you don't have to do it alone, it would be nice, but we gotta do what we can to reach our goals.
