How many hours a month would it take to run if you weren't focused on improving the product, just keeping the site running?

If the answer to that is a decent hourly rate, do that and then just start doing something else.

If it's not, and you aren't able to figure out growth, you may want to shut the doors, as I think it's not likely that you'll see a lot of buyers looking for $6K annual revenue, even at high margins.

I'm not that good at marketing either, but I'm having to figure it out. We programmer types think that "if you build it, they will come", and that a better mousetrap will trump any need for a sales and marketing strategy beyond a good checkout page. The truth is, if you don't figure out some of the marketing basics for yourself, at least enough to know what type of marketing experts to use, you'll be likely to have the same problems with your next venture. You might get lucky and stumble into a hot market, but if you don't, marketing will be the difference between being in the top tier making a double digit percentage of the available revenue in the market and being an also-ran making a pittance.
