I made some DXpedition verticals several years ago, and found two things 
most useful:

1. Pre-set the guy ropes as close as possible to final length. You can 
calculate using geometry or graph paper, or you can just lay the mast on the 
ground and do it full size (allow for the ground slope, of course). Then you 
can attach 3 of the four guy points and pull up the mast in the direction of 
the 4th.

2. Rope adjusters -- at the bottom of each guy rope, use adjusting blocks. 
These are commonly used for tents or other camping lash-ups. Naturally, you 
find them in the camping section of a sporting goods store or at a hardware 
store with a good sporting good section.
