Its hard to find and make a team from scratch. But dont simply rush people into a team as you will be spending a lot of time together; so make sure you have similar personalities/mental ages.
Also once you have a team then other commitments (usually work/family) become a real pain; so dont just settle on having the minimum amount of people required.
======================================
We (Rotten North), started in a similar position where 3 friends from a local area wanted to be in a team; we went to a local walkon site and met a couple of players who we met through p8nt and we formed in Nov 04 and apart from inferioir equipment compared to other teams at our level; the above problems were the ones that first threw a spanner into the works.
You have a decision to either sign up with an existing team or create your own with your friends; the former is the easiest and probably the most beneficial when it comes to playing ball, the latter IMO is more rewarding when it all goes to plan.
