computer drawing? - computer drawing tablet

Hey!
I need to finish a project ASAP. . .
I have to create a worksheet that outlines the 9 steps used for cleaning in the nail industry. UGH. . .
Sadly, I can't draw the rubbish that is worth it!
I'm really not sure how to do a worksheet if I can't draw.
Is there any suggestion about computer drawing for these steps?
What the hell are those wikis? ? ?
Thanks for all the suggestions!
