I have ALOT of experience with archives such as zip and rar, I made an archive reader in visual basic back in high school, in Collage I built a rar unpacker in c++ (which is the hardest format since its not open source), here a link [login to view URL]
Probably most importantly, I developed a comic reader for blackberry which unpacks archive files, and sequentially displays the images within. here is a link [login to view URL]
I can use an independent Library, or code one myself, just ask what you would prefer.
Since I am new to this site, i feel this is a perfect project to begin with, since Ive done it so many times in so many different languages (Actionscript, Java, C#, C++), not only will do this at one of the cheapest prices to get myself adjusted to the site, but you can have confidence that I know what I am doing.
Thanks for Reading.
