281412 Facebook application

I am looking for a desktop application (unless you have a better option) whereby I can run searches on various criteria (keyword, location, sign-in date, number of friend (min-max), sex, etc. and invite people to be a friend on Facebook or a fan to a facebook page. The solution needs to allow me to input and change the username and password of the facebook user or facebook page, and save the search criteria for previous searches so that the username and id and search criteria doesnt need to be input again at a later date. Other features/functions as can logically be expected. Please describe similar projects you have completed.
