I am the head of a magic club at my college and most of our members love to draft but most do not have the money to draft as often as we would like. We would love to just do some fun drafts but they are usually to expensive. I am buy any standard packs from mapped boxes. Message me if you have any for sale and we can talk about price and payment.
I would really reconsider this, mapping packs is pretty frowned upon, borderline illegal, and while there are still junk packs that people like to get rid of, most of these people try to get full price for them, since thats pretty much the reason for mapping the box.
What I would suggest is putting together a 360 pauper cube, which sleeves, box, and cards, can all be done for under 100 bucks and will keep you guys going for as long as you want.
I went and grabbed the most popular list off MTGS and deckboxed, then TCG playered it and I got this:
