PDF reader for android2

Hi, I want to have very simple android app that read PDF files and has the ability to: - move between the pages by touch - zoom in + out by touch - add drawing + highlight the PDF text I want it simple, so the PDF files should be in a specific folder (Downloads/PDF), and I want it to be based on open source projects, there are many such as: http://code.google.com/query/#q=pdf%20reader%20android [login to view URL] So I want you to customize it by using my design + add the three features I requested if the open source project doesn't support them. I need to finish it within 6 days, so I am only looking for professional developers :)
