make friends with the full timer at a sealer supplier. Most people instantly forget about where they started. use a 55 gallon drum, rig up the plumbing and a hose and use sand in the sealer. use a brush, Tampico brush is the softest one they make. If you use a brush the most you'll get out of a gallon is 60sq st. You'll have to keep the brushes wet all the time after the first time you use it. be creative and make a brush tank or pay about $300 Get a back pack blower, pass out flyer after you do a job, but don't leave foot prints on there sidewalks.
