Logo for online kids web site

Hi,

I require a simple, yet fun and creative logo for a new online web site targeted towards kids ages 3-11, but the product is purchased by parents.

I require 3 different mock-ups and then the one we like to be tweaked for use on all digital/print formats.

we have some ideas already which you can develop from but at this stage need a good price for something simple and potentially more work down the line as we develop the web site and packaging.
