Where to find cheap dog training?

I have a 4 month old yorkie,he is cute but the only thing is that he isnt potty trained. Im getting tired of cleaning up after him, I tried potty training him using a pee-pad.It doesnt work, he just tears it up.The only two choices I have is giving him away but I do not want to do that, or pay for him to get trained.I really want just to pay for him to get trained,but I dont want to pay like 100 bucks for it.Is there anyplace I can go to get him trained for cheap and I wouldnt have to pay alot of money for it.Another thing is there anyplace I can go to get him groomed at a reasonable price?
