Here is a clean, simple solution to your logo request. Seeing as how the name is "Simply" Bets, I think a crisp, clean simple brand would be most appropriate.
I have also incorporated the most common imagery people will find on your site, the odds logo (aka a colon). I hope you like them. Don't hesitate to request different colored layouts, as I would be happy to provide.
Ken, I see your contest is winding down. Just a heads up, that whoever is your top-ranked designer at your deadline can still submit entries for you for the 7-day selection period. You may want to make sure the winning designer, can also include a flat-color or one-color design in the file they send you, since all of these multi-colored and gradient-type logos can not be used for traditional printing and other things. If you would like to see any of mine as a flat one-color logo, just let me know which one(s) and I will be happy to do so.
Per your request, here is the black version without the website text. If selected, I will be sure the file I provide for you has both versions. As well as a version of just the "S:B" circle without any text at all. That way you can decide which of the versions to use, depending on the application of your logo (letterhead, business card, website, button link, brochure, etc.)
Here is how the logo could look in different colors as a flat one-color logo. This may be necessary if you ever emboss, engrave, or wish to do a one-color screen print or imprint on certain items.
I think the logo can still function in this simplest form, while still looking great and representing your desired brand/identity.
