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 o f 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. Se aled 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
