Replying to Backyard jib

ok......so, i have mono so i have to stay at home for 3 weeks (or more) and do absolutely nothing. i am now on day 4 and im going CRAZY. im sick of playing tony hawk and watching all my old ski movies. i got an idea to build my own rail in my backyard but i ahve no clue where to start.

all my friends have shit in the backyards, and all im looking for is some ideas, plans, suggestions on how to even start this project. i want to make a drop in and jsut a rail. i probally have all of the equipment needed (my dad..ugh, his garage...) so if anyone has anything for me...pleeeease help, im seriously going crazy.
