Javascript simple Parent Window

We are looking for a simple javascript parent page that has a relational update on a child window so that when the text that is on the parent page is updated the text that is on the child window is also updated to reflect the data that is on the child window. We require this to be the same as almost an rss feed .The relationship will be from a website to update the info on another website simply. The budget for this being that this is a simple project is only $30 we also have over 5 other projects and exceedingly much money in our freelancer account over $500 for other small projects so if you are interested then pm me. Only bid if you can do the project i do not want to hear any excuses. Pm me and let me know exactly how you will do it and the timeframe. Mimic certain or any information on a website that i choose such as time and date basically using tags in javascript to mimic Rss Update from one website to another.
