Even after you submit it, it'll take many weeks for it to kick in, so the sooner you submit your site to the search engines, the better.
Keywords and tags aren't enough these days. You have to work your keywords into your page text. If you sell handmade items, the words handmade should show up on your front page somewhere (instead of "made by me", for example).
Also, retain your copyrights. Get an agreement done up allowing them the use of your pile of flesh, but to keep the right to use - and sell - your pile of flesh elsewhere. If they want all rights to the pile of flesh, you should charge them more to take it from you.
The first thing that comes to my mind is embroidery hoops and springform pans, and although I'm not sure how the pans would work, you might be able to use the same kind of latch to tighten things up. Other that, some other mechanics would have to be involved, and I'm certainly no expert!
Go to http://www.cafepress.com/cp/info/sell/books.aspx. This is an inexpensive way to get a book published. Basically your only job is to market the book, but you don't need to purchase inventory. You purchase only what you need; cafepress gets their "cost" share, and you determine the profit above and beyond that by setting the selling price.
You can also set up a free account there to use as your website.
Kids like to have a feeling of accomplishment; sometimes all it takes is some participation. Let your laddie have a hand in making the lunch, even if it's messy (spreading peanut butter can be tricky, eh?), and he might find it more tasty. It could also interest him in trying something new that he wouldn't try before.
Cards and stationary are about the easiest things to do, as long as you go easy on embellishment and such; I'd go with self-printing for even less expense.
I'd make the cards out of a ream of Office Depot-brand, which is extremely cheap for 500 sheets, and you can always play with the rest; buy a box of appropriate plain envelopes. I'd try to use an element from whatever organization you're fundraising for to give it a sympathy/charitable angle; typically cards and the like aren't real RAAR grr ugggh sellers, but for a special purpose you could make a few bucks. Like if their logo has a heart in it, I'd use it, or at the very least use their colors. I'd print the charitable info on the back of the card.
