Design diy ceiling mount for heavy cabinet

[Alt-Bringer]

im wanting to hang a cabinet off an I-beam (steel) in my basement
looking at something like this http://www.standsandmounts.com/ioni...gedextendingceilingmount-luna-ceiling102.aspx
function wise, but also want an up/down (range of 2-3ft, from touching ceiling to droping 3ft)

the cabinet itself is a repurposed deep well window, and I am sure ill need to
make a metal frame for it to set into for support and mounting
i expect it to weight less than 150lb when loaded, but i never weighed the window
so id like to get as much weight support for the dollar i can

but i don't have 100$s just lying about to throw at this project

please help me figure out what parts id need and projected budget

Cheapest would be a rope, pulley and counter weight system.
