Selling items ideas? 10 items only

Guys I really need help! Okay so my community church is doing this sort of "Carnival" and pretty much we're in teams of 5 and we have to have ideas of what to sell that day. The problem is that we had to get a paper from this hat that had different themes of what to sell that day. BTW the carnival is planned to be in December. Our theme is technology and we don't have a lot of ideas so far. I really wished my theme was food or clothes. They told us that we can't be selling laptops or phones etc. You get what I mean. The only thing we can sell are accessories for the gadgets. This carnival is to raise money to give poor kids some gifts for Christmas. Pretty much because technology is very popular now in days they expect high number of selling in this sort of accessories. FYI our community is very large so this is a really high fundraising money.
iPhone cases (We're just doing iPhone in general for the phone accessories)
Laptop skins
Laptop cases
mouse
ear-buds (No beats)
USB Drives
laptop stickers
cleaning sprays and wipes
We need at least 15 selling items and I need your help we have to know by Sunday to get everything ready!

This is something very good you are accomplishing over there! Congratulations.

I would try eBay.com, placing low prices on my items to sell out fast.
Etsy.com can also be a nice option to sell your products.

Selling online can be a nice and fast option and you can also "google" for other stores too…

Hope i've helped you.
