68ft is scary. My shop used 4, 30 foot 12x19 beams back in 1984. I used a home built crane from 2, 4x4 douglas fir 16' sticks of wood, made into an "A" frame. I used a chain hoist to do the lifting, and another cable hoist to a tree to control the A frame location to place the beams. I had an oak tree luckily in the right place for that cable hoist to pull against.
Looks like your making progress, assume this is the hardest part of the project.
