You'll be bringing a lot heavier loads thru this door (both machinery and workpieces) so it would be nice to have a 10' door for more maneuvering room as you're backing in with loads. Both a concrete apron outside the door and a min. 10' wide rolling gantry are something to think about also.
I used the Harbor Freight gantry, which wasn't too expensive, but I had to replace 2 of the caster type wheels with straight ones to make it roll in a straighter line. ( It wandered all over the shop at first). It's great now tho, next best thing to abridge crane.
