Simple Logo Design

Hi, we are a sex education company called Stallion, and are looking to have a logo designed. The vision we have for this logo is a silhouette of a topless girl riding a galloping or bucking horse. I've attached a few samples, we are looking for something that is sort of a blend of these. We need this logo to have a very classy look and feel, and need versions of it in both black-on-white and white-on-black. Once the logo is designed, we need the coder to design 5 DVD box cover jpegs for us. These will not actually be used as DVD covers, just as gifs on our website. These can be very simple and it is fine if they all look the same, simply our logo with the DVD title written underneath. We will send the 5 titles to the winning coder. Please respond with samples of similar logos you have designed, or a link to your portfolio. Thank you and we look forward to working with you.
