Logo for website

I'm after some graphic art for my new website. I would like a WiFi (blue standard graphic) with a padlock or something like that. The logo should be quite large as it will be the main picture on the site's homepage, and my web designer will have links around it. I like cartoon type look/feel. I would also like a web browser icon, and a small version of the icon for business cards/invoices, etc. I would also like a pale? version for use as background/watermark art.
