Where and How make an auto template generator ?

Hi to all,

Here is the trouble
i have a template with 10 casinos, and i want to generate a special new template and different descriptions each time.

Because do it by hand imagine the time you need too ?????

Or it's better to make 1 page per casino or a template with 10 ?
(when you look online in this keyword online casino some have template others only 1 casino)
