Hey, beauty is in the mind .... etc.
I think that SexyLogos.com is a terrific name. I don't care how many links or type-ins or whatever it has associated with it. This name is a winner!
Now, take a little time and develop a GREAT logo to go with the name. You simply cannot skimp on the logo for a site that is offering to sell classy logos to others. Create some examples of the types of work that could be completed by the artist or artists at such a site, and post them, with lush backgrounds, lots of space, as if they were works of art being displayed in an art gallery.
Keep the logos VERY classy, up-scale, slightly provocative, yet understated. Pitch the logos as examples of slightly erotic original works of art, and price the Logos on such a site at a prime price. Show people what they are paying for by having their logos designed by real artists.
With just a little bit of thought and development, Voila!!! You have created a buying niche for the products of your web site. Whatever you do, don't underprice either the logos for sale or the name itself .... you will only convey to potential buyers that your product is "cheap" or "worthless."
But, ah ... with a lovely artistic touch, lusy backgrounds, rich colors, and understated text ... plus logos that are one of a kind logos, such that once one is purchased, it is gone ... forever, a unique, original, one-of-a-kind snippet of high quality art work that can be acquired by a web site owner, even if doing so must be approached as an INVESTMENT, rather than a one-time purchase ...
It's all in the approach, as I see it. Good luck to you and enjoy!
