Arthur...to be invited to fish for a team you have to have proved your self a competent angler.Ie by winning opens and general being a skillful angler.no one is trying to make you do anything you dont want to just trying to make you aware you cannot start at the top you have to work at it and put in lots of results and time.Just by traveling on public transport limits you to venues and start times .I think you first move is to join a local club to you.(so u can attend meetings and outings ) and maybe team up with some one who can give you a ride to matches.As you have admitted yourself you have been out the sport several years .so much has changed it really is a big step you need to get back into it and see what its all about again.........this is not a put down just trying to make you aware of the pitfalls.
