You have a great catchment area to be fair with no real rivalry, there are a lot of clubs with smaller scope ahead of you in the league structure. Getting some sort of additional investment is a must but shouldn't be out of your reach. I think the ground should stay where it is too, not a great deal of room for expansion, but you don't want an out of town soulless bowl like Reading. You have greater potential than a second Bristol club in my opinion.
