I built an 8' v nose on top of a frame like the one from Northern Tool. Put plywood on the floor and made box sides with a shelf and rear doors. With the v nose its about 10' along the centerline so i could fit the bigger jets in. The shelf slides right out complete with the jet it's holding. i used to tow it with a VW TDI (100 hp Diesel) Jetta no problem and the Mini should be fine with something this size.

I like that Snowmobile trailer with the clamshell, it's just too bad the hood doesn't open more. You will find 8' too short unless you are flying only 18-20 lb class jets.This trailer from Canadian tire looks good but length may be a problem:
