She will need to be 6 months old before you can show her. I would first of all find a ringcraft training club near you, the Kennel Club will tell you where if you ring them. When she has had her jabs you can take her there for training and they should be able to advise you of shows in your area, they usually have schedules for local shows. Failing that, you will have to buy Dog World or Our Dogs to see where the shows are and send off for Schedules.
I am assuming your collie is Kennel Club registered, if not you will only be able to show at companion shows.
