You estimate how many hours it will take you to empty garbage cans, vacuum and mop, dust surfaces. You should have a rough idea from what you normally clean. This is no different and probably a step up for you to make more money. Do a walk-about there and take a good look around, you will figure it out. Of course, now you are into the big time and will have to invoice, charge taxes, etc. You will probably need to apply for a business licence if you dont already have one. You should look into that aspect.

I agree with figuring out how many hours it might take you to do the job and figuring your bid based on that. Whether or not you will need a license for this, you would need to be contacting the city officials where you will be doing the work. For labor, it would depend on the tax laws where you are working as to whether or not you would charge taxes.
