Any Fundraising Ideas?

I am in my high school's chess club. Since the club is relatively new, all we have are 10 chess sets and a few working clocks. We are planning on joining some tournaments in the future, but have very few current funds. Since we need to pay for buses, entry fees, and new clocks, what are some fundraising ideas we can do to get money? (We have 15-20 members who can help)

Any ideas, no matter how hard, would be appreciated! We could definitely try many different things before we find one that works.

Buses are expensive.  When I was in high school, some of the older kids had access to cars.  

We played other schools.   We had a league of schools.   Most of the other schools in the league weren't more than a half an hour away.   

It cost very little. Chess, in general, costs very little.

I don't know where you live but presumably your school plays other schools now in sports.  Get a list of the other schools that your school is already playing.  

You could play online but there are potential problems with that.  Live games still have certain advantages.

Let your strongest player play simul on 10 boards with $5 entry fee, draw = money back, win = double back: $10. If your strongest player wins all 10, then that earns $50, enough for a clock.

We did online matches last year, but this year we are planning on playing in person. Busses cost 25$ an hour, so even if the school is 20 minutes away, for each meet we would be spending 50-75$
 

That's a great idea! We will definitely do that! Any more fundraising ideas we can use?

Everybody could get jobs (part time, nothing major) and chip in 50 bucks. Any kid 10+ years old can make at least 50. 

Yeah, that could work except most kids probably don't want to spend 5 hours in their free time working.

You could also take your strongest players with working clocks and chess sets to a park and challenge bystanders for blitz games at 1$ each. Make it clear that the purpose is to buy clocks.

Money is always the easiest thing or the hardest thing.  

First thing. chess club are always one person away from closing.  So, find that one person who is willing to put in the work to keep it going.  

Next, don't just say money, figure out exactly how much money you need.  You need X, Y and Z, then find a price for it.  We want to go to X tournaments, and we need Y this to get there and Z equipment.  I don't think it is unreasonable to say you will give X people for free or low cost, and then anyone above is bring your own equipment. 

Then hit up the school, students and parents. See what the school will give you, if the students will part with some funds, or their parents. 

Followed by local businesses.  Get that sweet, sweet sponsorship money.  Liquor Emporium Chess Club.   

At that point, figure out how much money you need.  You can shovel snow, rake leaves, cut grass, sell candy bars, run a charity night at a local restaurant or bowling lane.  etc. 

A lot of titled players will play simuls, where they take half the entry fee, or charge a flat fee and your club gets the rest.   

Isn't this what Indiegogo or other crowdfunding sites were for, originally? Get an adult, calculate needed funds, make a video explaining what for and spread it among your local community, school and chess community. Don't make any physical pledges beside some kind of "thanks" for backers, have flexible fundings limit and good luck, have fun.
