Made contact with a guy that owns several shopping centers. He sent me immediately to one of them for a quote. Could lead to more work if i get this right. The surface is about 14 x 350 with pillars every 20 feet and a painted ramp between each. I plan to bid $375 for this job. Looks like around five hours. I am a rookie and could be wrong. Am i way off on this. Any advice would be great!
