API to bost website blogs and videos to blogger, youtube, and more

I have a website that has various blogs added to it (in the database) and I want to be able to publish these blogs to Blogger, WordPress, and anywhere else I can as soon as I click Submit on the input form. I also have a video gallery and want to be able to dynamically post the videos to YouTube and any other video sites after the Submit button on the input form is clicked. Both blogs and videos need to be able to send keywords, tags, descriptions, names, and whatever else the websites will accept.

Freelancers- bid on this project. Webmasters- post a similar project.
