If you're just starting s team, the first thing you should do is figure out what level you want to play at - local events, regional series, major series, or all of the above. This will give you an idea of your costs (entry fees, hotels, travel, etc) and the commitment level (practice schedule, how many tourney per month you can do, custom jerseys, etc). Costs will usually depend on the level you play at. The bigger the tournament, the more it's going to cost.
If you're a new team, sponsorship will be tough unless you have connections in the industry. Most sponsors want to see some proven results before they start dishing out the goodies. You can start with your local field. Many fields will give home team sponsorship in return for working there one or two days per month. Generally, home team sponsorship means you get reduced prices on play fees, paint and sometimes equipment. You can also try local businesses outside paintball. If you do get sponsors, make sure you promote them with a banner and/or logos on your jerseys.
The individual players level of experience should be taken into account when you're deciding on tournaments. You should try to play tournaments everyone is comfortable with. That may mean you go to some local tournaments first to see how good you are before going to a major tournament. Starting with a major tournament and getting your butt kicked all day long may not be everyone's idea of fun
Whatever happens, remember it's a game and have fun
