Theme suggestion for a small computer business site

He there, i am not sure if it is allowed to post a question about theme suggestions. If not please accept my appologies!

I am starting a small computer repair shop and was wondering if there are any business like themes-styles for wordpress.. Coming from the Mambo world where these themes are available, i was wondering if there are any for wordpress. The only one i could find was the Technology Bytes theme. But i love to hear your suggestions!

Kind Regards
