Company logo

I need a primary & secondary logo designed for a small computer systems company. Basically we supply software solutions to other companies. Reporting, ERP, accounting, installation etc The logos needs to be scalable, I.E NO jaggies or bitmaps and also needs to be printable via normal professional printing companies for things such as business cards & letter/invoice headers the design needs to look professional , so no cheesy artist designs or ideas thank you. A few rough sketches of various designs would be fine, followed by the final job. I will give the name of the company to the winning bidder.
