523455 need google keyword checker script

I need a way to automatically check keyword rank for my clients. So if i have a client with a website [login to view URL] and i am doing SEO for 20 keywords... i do not want to check manually 1 by 1 what positon they are on Google, i need a way to crawl google and it finds the position automatically for me. It should also tell if it was a organic listing and/or on the google map. it should also say what page number it was on based on 10 result search page.
