Embed Widgets for Blogs and Websites

I am looking for a coder that can create 3 different embed widgets for blogs and other websites to use on their site. I want references and links embedded that link back to my site naturally. Widget is to be hosted on my site with an embed code for user that will disable its function if the user alters the code in any way. Typical stuff applies, the purpose is to allow users to utilize some of my content on my site by putting my widget on theirs. I need SEO purposes applied to this as well, I want to have my links picked up by search engines so some JavaScript and Flash based widgets may be an issue. You will need to discuss with me the various options you are providing. I am not concerned so much with the content of the widget for SEO, but am concerned about the links back to my site. If you have a different idea or alternative, I am open to ideas and options. Escrow based off of percentage of project completion only. Must have Skype capabilities for contact only.....no email or other instant messengers are used. Just Skype for quickest results. So you must have an account.
