It has become very expensive to ship the 8 foot tall roof towers! If you can buy the 8 foot tower legs locally and drill the holes, I can cut, drill and ship you the shorter parts at a reasonable cost. 6061-T6 aluminum angle can be purchased through OnlineMetals.  They have warehouse locations in Toledo, OH; Wallingford, CT; Atlanta, GA; Dallas, TX; Los Angeles, CA and Seattle, WA.
