There are 3 main aspects of organizing this tournament: Participation, Cost and Promotion.

PARTICIPATION
It depends on how many teams you're anticipating. Ideally 8, 16 or even 32(too many) would be a nice figure.
Then set up the schedules in a grouping format (4 per group) with the top 2 from each group heading to the knock-out stages. The grouping format gives the best level of satisfaction for participants because each team gets to play a minimum of 3 games.
The time allocation should be 7-1-7 (7 mins per half). Thats just a suggestion, 5 minutes or 10 minutes may also be applied.
With this format a 8-16 team tournament will take you 6-10 hours, with substantial breaks in between. Is that too long?
It's up to you to decide, maybe reducing game time, or having less knock-out games.

COST
The main part of the budget is usually the rental of the court and equipment.
*If you've gotta a free court/field, then all the better.
From here you must calculate the participation fees, taking into consideration how much you are targeting to raise.
– Remember, the participants satisfaction is always first priority, so whatever you plan to charge for participation, you must give back in other forms.

Compulsory items for the budget would also include medals for the top 3, as well as water for the teams. My suggestion would be giving consolation prizes to all the teams who made it to the knock-out stages, as well as giving a token of appreciation to all participating teams, for supporting your fund-raising efforts.
Good forms of prizes would be hampers for the teams (ranging in sizes).
Another idea would be recognition of the Golden Boot(top scorer), Best Player, or Best Keeper. All up to u, HAHA

As this may turn out to be a big event (I wouldn't know), what you can do is apply for sponsors from local companies. It will be good publicity for them too.

PROMOTION
How successful you tournament will be, will depend on its format, and how you promote it. Get more people involved, and it should be a big hit.
For example, having the Guys' team help out wouldn't hurt a bit!

As for the food, I would suggest opening up tenders. Your friends can come by and open stalls, while paying rental fees. The usual stalls would be snacks, drinks, popcorn, hotdogs… etc2.
If the tournament were to be very long (which may not be so good, if you're just playing for fun), the stalls should also sell heavier meals, such as lunch menus. Burgers, etc. Remember that there will be very hungry spectators around too!

I think I've stated more or less everything you'd need to know about organizing a simple soccer 5-a-side. For info on rules, do surf the FIFA website.
Good luck!

I would check with either your coach or athletic director. Although refs are supposed to report ALL cards, sometimes cards in tournaments aren't reported. If it wasn't reported, don't worry about.
