create backlink finding software

im looking for someone to create me a web based software that lets the user finds backlinks. the easy way toi do is is they would have a box that they can type a keyword in then a choice of buttons depending on what type of back link they want to find. so for exmple if they wanted to find finance edu blogs to post on they word type "finance" into the keyword section then click on edu blogs and that would do a search in google with this text: "finance" site:.edu inurl:blog "post a comment" -"you must be logged in" this would then find them and list in google all them type. I want different buttons for different back links types so would mean each button would be a different seach in google.
