Help me write this :)

Hey guys, I'm working on a song..Well, an idea for a song, and I can't seem to figure out how to write it. It's just a few measures that I need help with.

It's called "Give Me a Hand"

I know what notes I am playing, I am just unsure of the duration. The reason I ask is because I like to write on Guitar Pro 5, makes it easier to write all the parts for me.

Anyways, if any of you guys can figure out what beats I'm playin :P that'd be great. I need the muted parts too.

Thanks

Taso
