Gaw miners is a company that sells miners. Just google them. Why sell miners? Because that's their business model and how they make their money selling their products.

They do cloud mining, they are not ASIC manufacturers.

Oh, I thought they manufactured them. I guess to answer op's question then is they just make their money from taking their cut, but why don't they just mine the coins themselves instead and keep all the profits? Well, they probably take a big enough cut to make a big profit. Many cloud mining sites are virtual ponzis though and don't even have any miners but just pay out users from other investment so be careful with them (not saying gaw is a ponzi btw).
