Logo re-working

School Stickers

We're a sticker manufacturer selling solely to UK schools. You can check us out on http://www.schoolstickers.co.uk

Teachers. Providing to kids between 5 and 17. Aimed at adults NOT kids.

We want our current logo reworked. Same colours and same overall structure of text and sticker outline. But we want to include .co.uk. To do that we want to move the STICKERS out of the sticker; and instead put in ".co.uk" inside the sticker.
At the moment we would like to keep: The colour; the "Sticker" text, the actual sticker and would like to change: adding .co.uk and moving STICKERS. (Although we can be persuaded to change that idea).
We've tried to do some stuff internally (attached) but they lack the design sophistication we are after. Looking for a design that builds on our current design elements.
The logo will be used on all our letterheads etc. and in our new website: http://schoolstickers.fdlab.co.uk/ [Currently in development - launching in the next few weeks]. Old website is on http://www.schoolstickers.co.uk.
I look forward to your ideas ! And really look forward to a more sophisticated logo ! :)

Note: We are keen to have the font size of all elements the "school" "stickers" and ".co.uk" roughly the same size.
