Here is the logo I came up with for your site (cool idea by the way!). I wanted to make a horizontal layout, as it lends itself to being placed throughout a website quite well. I replaced the "i" in "Winners" with a triumphant/winning guy, and I replaced the "s" with a dollar sign. Let me know what you think and if you want to see other color options. Thanks in advance!
