RSS feed link customizable to multiple search words

I need an RSS link that’s customizable and acts as a filter so that I can point to any news website and this link needs to be customizable such that I can choose which words/acronyms I will receive breaking news on. This link code must allow me to insert 2000-5000 search items and as part of the project you will instruct me where exactly in the link code I can put these words/acronyms and where exactly in the link code I have to change in order to point to a different news website. You will build it so that I can use it for any news website? You can test your work on any feed reader such as “Quite RSS” or “Feedreader” and you can point to such websites as [login to view URL], [login to view URL] I was hoping to hear from you that you are sure it can be done and that you are sure you can do it. I just don’t want to go ahead with this if we have to eventually abandon it. I don’t have that kind of time to spare as I am working on other projects myself. I hope you understand… Also please understand that this quote is for the complete job price. It is not an hourly rate…
