Urgent Illustration Required, cartoon IT/Network drawings

I have a presentation with some old diagrams, I wish to update these to a more cartoon like style - still needs to have a corporate feel but a bit more interesting to look at visually.

I have a style in mind and will work closely with you to ensure that each part is completed correctly. We can create each image separately e.g. server, database, user, hacker - then piece it together to make the full diagram.

www.cibecs.com the see how it works video is a good idea of the style - the hand drawn diagram in the images or the toolkit image is also a style I would be more than happy with. The diagram.jpg with the bad standard images of people are the type of diagrams I need to fix - there are about 7 of these.

I need to see examples of work to ensure it meets the standards that I need.
