blow dryer info needed

I don't have an "easy" way to wash/dry my dogs, so they don't get it nearly as often as they need it! With my neuropathy it is hard for me to undertake getting down to the tub. My dogs hate a bath and are not cooperative at all. Then when it comes to drying them off- it gets worse. The corgis have a double coat, so maybe those of you who have double coated dogs can help. It takes them FOREVER to dry, sometimes 2 days. They won't let me near them with a blow dryer. I attended a dog show recently and saw them using some high powered blowdryers that blew the water out of them. You could see the water flying ! I was amazed !!! Can anyone tell me how expensive these are? Is there anywhere us "poor retired " folks with almost no income can find a reasonably priced one?
