I understand your situation, go on youtube.com and check out training techniques. There are many methods, to teach your dog, go to bookstores like landmark if it exsist in your city, you will get many books.
Best way is to see the techniques on youtube which will help relate you better.
I am saying this since one of my friends paid 10000/- to the trainer and what he taught was only handshake and sit command, which are fairly simple.
Hope this helps.
