If you actually have an organized competitive tourney team look into getting into the SYNC guild. All of the major teams set up scrims through it right now.
I think the lack of ladders is part of the problem. While the desire to be a legitimate e-sport is admirable ont heir part, I feel sPvP is generally been a failure to capture many peoples interest, and part of the problem is the lack of Ladders/ELO. Ladders bridge the gap between the serious "e-sport" players and the super casual I am just here to try this out players. I lost interest in sPvP immediately when I realized the rank system was nothing but a grind with no matching and tPvP was entirely random.
Anet appears to be avoiding ladders with no mention of them in the most recent post, and I think that is their loss as I believe most players are like me who really could care less about "e-sports" and simply want to be able to join up and play fun games, form a team play teams around my skill level no matter how low or high that may be. They are basically cutting out what I believe to be the largest portion of PvP players and making it simply way, way too niche.
I still play for fun as the casual PvE matches my busy lifestyle and I do find WvW fun. But sPvP simply lacks too much structure for me and I am not interested in being serious enough to be networking with other serious pvp players to do scrims. I think a lot people probably fit my description, and most likely quit to look for the next thing or go back to WoW. I don't have confidence Anet even had ladders on their radar as it seems they have decided they are evil.
