Wow!!!!! That sounds so awesome!!!!!!!!!!!!! A lot of money but I think well worth it.
Here are a couple ideas for fund raisers from my high school and college days.
when I was in high school I think the parents booster club for the foot ball team made a decent amount of money by creating "noise makers" to be used at the games.
They were these really big tin cans that had little rocks inside them and then at one end of the can a hole was cut where a large dow rod was inserted to make a handle. The cans were decorated in school colors, logo, etc. painted on and had streamers stuck to it too. They were really cool. I think I probably still have mine some where. Maybe you could do something similar for your college sports events. I would check to make sure though, that they would be allowed to be taken into the game. I think back then (10 years ago) they charged $10.00 a piece for them but they were really cool.
In college we did bake sales, raffles, "cow pie lotto", we had a bunch of baseball caps made with our College name (Penn State) and then underneath it had the "College of Agriculture" underneath it. We sold these to other students in the college of Ag. and made a lot of money because we were the only ones that you could get such a hat from. Maybe you could do a hat with your college and "school of nursing" or if you go to a place big like PSU "College of Sciences".
We also did Chinese/Silent Auctions as fund raisers. We would ask for donations from local businesses or ask that they give us items at a discount. We also had alumni create and donate gift baskets and then we had an auction.
Basically, you line up all of the items around a room and place a note card or piece of paper in front of each item. People can walk around and if they are interested in an item write down what they are willing to bid. Then, if someone else comes along and likes the item they can write down a higher bid. At the end of the specified time period the last person on the list (with the highest price) wins.
I have also seen this done as a raffle. Coffee/ tin cans were placed in front of the items and people would buy so many raffle tickets. They would place their ticket in the can of an item that they liked and then at the end of the period you hold a random drawing from each can. Who ever's ticket is pulled wins the item.
I really like those types raffles and they can be a huge money maker depending on what types of items you raffle off and how many people you get to come. Items that I have seen auctioned/raffled off are gift certificates to hair/nail/spa salons. Getaway weekends at a nice local hotel, Certificates to florists, gardening places, restaurants. Items like Lenox clocks and figurines, professionally upholstered stools/benches. Gift baskets with different "themes" ie. a wine basket with wine, cheese, and glasses. One for the kitchen with cute little tea towels, tea bags, cups, etc. Christmas basket with ornamnets, music CD, etc.
Since you are going on a "mission" I wouldn't have any problem asking your local churches for ideas and assistance in raising money. I'm not saying they should just give you money flat out, but they may be willing to let you in on some of their fund raising activities.
At my church we often have people come into church and before we do the collection they will get up and speak to the church from the podium, explain what they are doing (going on a mission, trying to send the youth group some where, sending money to Appalachia, etc.) and then they will have a second seperate money collection during the service where that money is given specifically to them for their cause. Maybe if you or any of your classmates allready belongs to a congregation you can ask your pastor about this and see if your church can help you. Our youth group frequently sells donuts and coffee after mass as a fund raiser. And don't feel weird if you or some of your fellow students belong to a church or are not religious. I can't tell you how many people in my church see me in my uniform at church right after clinical and say "nursing, that truly is it's own mission". I think you would get a lot of support if you explain where you are going and what you will be doing.
