Logo for start up

Hi

Logo required for new online venture. Am looking for simple clear design that will go with a very simple uncluttered website.

Logo will be used predominantly online (website/emails) but should also be usable for print media.

My initial thought is that logo will have a simple symbol to go with name (website address) and tagline.

I really like these logos
overpopulationisamyth.com
http://www.peoplepowerco.com/
... as well as famous brands like amazon/nike/fedex

Audience is predominantly over 25.

Will evaluate bids based on
- previous examples of logos created
- positive site feedback
- fast turnaround

thanks

Mike
