Gary,
The Willowyck kennels have an excellent reputation for the quality of their dogs. I presume from your description that the sire of your dog is FTCh Tasco Monk of Mansengreen. He's a superb young yellow dog, and a friend of mine used him as a stud after recommendation from some well known gundog trainers. I have one of the resulting pups (now 10 months) who is proving to be a delight to train.
You certainly shouldn't go wrong with any help from the Willowyck kennels. Alan Thornton has helped to teach some of the leading gundog trainers, and you'll find Ricky Maloney to be very helpful as well.
My advice would be to give up any thoughts of trialling your older dog, and just try and see if you can teach him to be a useful gundog. This is possible (but won't be easy) however, the lessons you learn from your older dog will be invaluable when you come to train your pup. If you can get the older dog to a standard that you can take on shoot then this will give you a grounding in the world of gundog work and shooting which will make you progression into trials much easier.
Getting membership of the gundog societies can be a hurdle as often you need a countersignature from a couple of members. My advice would be to ring the secretary of the society and ask if you can go and watch one of their working tests. These are held during the spring and summer. There you will be able to watch the dogs being tested, and meet some people that will happily countersign your application. Many people are put off by the need for counter-signatures, which is a shame, but it's not that hard for someone who is prepared to put themselves out.
The United Retriever Club is usually a good start, as they are divided regionally and hold training classes. They have a website where you can get details of the region most appropriate to you. Link :
http://www.unitedretrieverclub.co.uk/Advice for training your pup and older dog is a bit big for a forum reply, but as well as joining a couple of gundog training classes & clubs I would recommend getting some books and videos / DVDs.
As a start I'd recommend 'Retriever Training' by Nigel Mann as a nice, fairly concise book and the 'Drakeshead Way' videos (get both the basic and advanced ones). Do a google search on 'Paul French Video' and you will be able to get the videos.
Hope that helps...
