The most important thing you can do to make house training happen as quickly as possible is to reward and praise your puppy every time he goes in the right place. The more times he is rewarded, the quicker he will learn. Therefore it's important that you spend as much time as possible with your puppy and give him regular and frequent access to his toilet area.
Before enrolling with a particular club contact them and ask if you can go to watch a class without your dog. This will help you decide if this is the right environment for you and your dog. Some clubs have waiting lists and you will need to book ahead, some accept people on a roll on roll off basis. Prices will vary from a joining fee and then weekly payments to a one off fee for a certain length of training.
