Material list for mini ramp

Hey guys I smoke a lot of weed and don’t really build shit ever but with the materials list and the time I’ve got here I think I could put it together.. I wanted to pick everything up from Home Depot and order the skate armor online.

I wanted a 4 feet high 8 foot wide ramp. Length 24 feet.

What materials would I buy to build this..

Thanks :)
