Hi guys, new member here. I appreciate all the knowledge! 

We usually do small residential job or commercial, nothing ever close to this size. 6700 square feet of limestone at the Mandarin head office and flagship banquet hall. 

I've attached some pictures. Various cracks some hairline, others a bit larger. Traffic areas will need a grind. At least 800 grit, however there's a some deep stains and etches scattered in the lobby and hallways. Bride and Groom rooms have bathrooms that are destroyed. 

I know I'm competing against the company who did the work 9 years ago. They're a franchise and much bigger than my company. I already know my price will be more so I tried to sell them on out workmanship. 

There will be three hopefully four working. Two machines, two vacuums. 

I have prepared two options.

A) Clean, polish and fill cracks and holes but not level them flush with the floor. Sealed with clear penetrating sealer. 

B) A full restore and make the floor look brand new again. Resurfacing to a high polish finish. Cracks and holes and ground flush with the floor and of course sealed with clear penetrating sealer. 

Oddly enough I learned this trade from Dana with the monkey pad system. I love the pads for honed and patina finishes but I can't figure out how to get a clear polish finish with the pucks and 11000 pad system. I have a klindex machine that wright's about 150 lbs without weights. 

The polishing compound is KP85 made by klindex. It's a bit of a pain to work with but I love the results. 

Pricing. I never ever do square footage pricing but for an area this big I need to justify throwing costs. I was thinking $2.00 a square for option a. $13,400 total. 

$3.50 a square foot for option b. $23,450 total. I know not every foot would have to be ground so I was thinking $3.00 a square foot but then I'm thinking why only a $1.00 more for a full grind. Clearly over thinking thus lol. 

I'm assuming it would take 4-5 days for option a, 7-8 days for option b. That's a complete guess. I never restored this much marble at once before. I like to gross $1000 a day on residential job but think I should make more on a larger commercial job.

Any input would be nice. I'm not going to crystalize.

Thank You
