Web based application

Hello...I am looking to develop a web based application. ? The focus should be on simplicity and style. I would like the application to: -automatically keep track of keyword rankings for inputed websites for a variety of search engines - namely google, google adwords, google local, bing and yahoo organic and paid -be able to use Google's API to do keyword research and then take the suggested keywords and automatically look up competition (both for SEO and PPC) -track backlinks to and from inputed websites -generate a variety of gorgeous reports of tasks above to html and to pdf -need to have a scheduler to schedule report generation at regular intervals in the future. -the program should be web based and have an api available so that it can integrate with other programs in the future. I want this to be very simple, stylish and 'just work'. This is a single project but would be happy to find somebody long term. Thank you.
