joomla 2.5 component needed - product comparison

Please refer to the document attached this is the first step of a project, im on budget so please do not overprice this project if u want to work long term with me. description: i need a component for a joomla 2.5 website This component will enable people to compare products by giving an importance mark for choice criteria scenario: for instance, i want to compare 3 different cameras: 1) in the interface that you will be coding i will be able to type my search title like that: ie: "comparison between cameras" 2) i will add the category of products i want to compare by typing it in the field, here "camera" 3) i will add the products that i want to compare in the field on the left and it will save it in the right box when i press enter (with "tag" saving effect just like on youtube for instance (each time i press enter after a word is typed it will add a box around the product, and then i can type another product...) please see doc attached. there will be a little cross on the product name to delete it if needed. a suggestion list will appear for past typed product names (saved in the database) 4) i will then add my criteria. it will work exactly like above 5) a general board will appear with the data previously added. colums will be for product names, and rows for criteria 6) five stars will appear for each product/criteria group. the stars will be white but with a roll hover effect that will fill the stars with orange color. when someone click on the 4th star for exemple, it will fill the first 4 stars. when clicked, it will save the number "4" in the database as a mark. 7) Saving the project as a joomla article. the overall sheet can be saved as a joomla article for further consultation. a url will be generated so that people can share their simulation with others or view it later. 8) please make a clean/modern presentation thanks
