What dogs do you have and how old are they?
If they are from working stock they will have it bred in them.
If you do not get any offers why not go on your own, yes sure you will make mistakes but learn from these, get a good book, visit game fairs or hunt shows, Terrier lurcher shows local to you, this will get you mixing with people with the same interests.
Alternatively go beating on a local shoot?
Good luck in your search, it will be worth it.
