Trailer open 6*14 or thereabouts - $1000
Turf Tracer HP 52" - $5300
Metro 32" - $2100
Redmax 7001 blower - $500
Good trimmer - $300
I think I spent $9200. With the other $800, a roll of trimmer line, all various hand tools, eye protection, $60 for peltour worktunes for ear protection, trailer registration, and oh yeah, sulky or pro-slide.
Now you're full in business, I would take out a personal loan from somewhere, somehow to get liability insurance, pricing varies by your area.
