Logo Designer Required

I need 2 new logo designs for a company which resembles the uploaded sample logos. One logo should have the company name below it, and the other one shall not. The difference between the samples attached here, and the logos whic you are required to design is that you should replace the lion head in the sample with the head of a bull (with horns). The bull needs to be a strong and dignified bull (like the lion is), and not a slim or weak looking bull. YOUR BID WILL ONLY BE ACCEPTED IF YOU POST LINK OR IMAGES TO PREVOUS LOGOS THAT YOU HAVE DESIGNED. The company is a new professinal services company that shall sell its services worldwide. - We shall gain the copyright and all other rights to the 2 logos. - You must supply the original files for the design (i.e. vector graphics) that will allow us to scale the logo. - You must supply the logo in multiple resolutions. - The very low resolution version needs to be very similar to the high resolution version. - If the logo is based on a 3D design. Then we need a 3D file in one of the following formats (wrl, skp, 3ds) Good luck!
