Use "thinkphp" development of consult???

So, our team is going to do such a major station (Nature is Enterprise product category):
Like 58 of the same city, buy nets, soufun such a major station,
First there is a master station, then each province city has a two-level sub-station, each city sub-station site style layout unified, the content is different. May I ask think to make it?

My mind is so conceived, but also please correct me, thank you!
1. Complete the project using separate groupings.
2. Home Main station on home default group
3. Each city exists as an independent grouping and how many cities there are, and how many separate groupings are added.

And then about the database design I think so:

My main station has n tables, and then each city sub-station copy this n table structure, and then add their own data, if there are M cities, then I will have n*m table,,,, this will be a vast project, I do not know if I have such a design problem? I implore you to enlighten me! Thank you!

Reply to discussion (solution)

1, each city sub-station site style layout unified, the content is not the same
Is it possible to think that a single set of templates can be shared by a station

2, each city sub-station to replicate the N-sheet structure
Is it possible to assume that the processing of the N-sheet is the same

3, each city as a separate group exists
Would it be considered necessary to assign the same code to M sets

I think this should be a data storage problem and code templates are not related
