Android Facebook and Twitter developer needed ASAP

I am looking for someone to add simple function in my app. You should be expert in Facebook and Twitter developing of android. 1. When you press button, if Facebook native app logged in already, we should retrieve facebook id and username without login in your app. If not, show facebook native app log in dialog and after log in we get id and username. 2. If Twitter native app logged in already, our app send follow request to somebody with your logged in account information. You can sample twitter username for somebody. If you are experienced in this area, you can finish within 2~3 hours. I need that in a few hours. If you can't, don't bid this job.
