well if you are asking for an appraisal, i'll say low to mid $xxx, it is a dating website but you can develop it more and get more traffic, the price will jump, it is a pr3 site too, so good job and good luck, and dam, 350 uniques a day is great, about 250 a day more than my site
my estimate for that is around $200 to $600, it is a good pr so far, develop it a little bit more, put a little more time on it and price will rise fast like stocks, it may come down too lol, beware of that
