Facebook chat intregration

I am looking to have Facebook chat integration implemented to my website www.CreepyCupid.com. This website allows users to post messages regarding online dating and then comment on the messages. Currently, the comment system is not facebook integrated and is based on the php script from [login to view URL] I am looking to give users the options to post through the facebook comments (this code is already provided by facebook) or if they don't have a facebook account, users can post through the normal functionality of the site that is already setup. Facebook comments will be listed above the comments posted through the normal functionality. Currently, there is a counter that lists the number of comments. I would like this to list the total number of comments posted through Facebook & the normal functionality of the site. I would like to allow a function to allow users to post quickly via facebook comments similar to how it works on [login to view URL] This site allows users to click the comment button and post comments instantly without having to click directly into the post. If you see how it works at damlol and click on comments, you will see a comment screen expands when you click on it. I would still like to give the user to go into the actual post as well to comment in addition to have the quick pop up comments. The budget for this project is $60. I would like it to be done within a week. I don't want the coding to interrupt the normal site from functioning since it's currently up and running and has users. You will have to have the skills to be able to work with the code that is already in place from this scrip that is based on a framework scriptolution
