Bath towels: 2 or 3 for use as drop cloths inside homes.
Paint brush, bench brush, or cob web brush for wiping sills and dusty fames.

Triumph 6" scraper + a pack of stainless steel blades
0000 steel wool
White scrub pads

2 Packages of extra squeegee rubber (Black Diamond is a good bang for your buck)

Extension pole: 12’ of the same brand as your squeegee and mop handles so the tip fits just right.
Ladder: Werner 13’ multi will get you everywhere you need to be below 2 stories and will fit in the backseat or trunk of a car.

Spend the rest of your money on door hangers and business cards.
