Big question as many things have to be in place to make the team a success. First you need a filed to practice on. Then you need players. There are web sites like Eteamz where you can post your tryouts. For travel teams where I'm from try outs are usually August and October althoght some go on year round to fill in spots. Once you have a team, us can use the same web sites as thhey post tournaments in your area.
This is just the basics. You need a team manager, player dues to pay for tournaments, uniforms, equipment and lots of time.
