I wish I knew more about Labradors! It does sound like you need someone to take you under their wing and guide you.
Have you looked to see if there are any shows near you? Go along as a spectator, buy a catalogue, take a pen! and tick off any dogs you like the look of. Then see if you can get to speak to their owners before or after judging.
If they are too busy to talk, then you may have their details from the catalogue to write or phone, or can look online and send them a friendly email.
Above all, have patience :)
