I found that the holder needs to be fairly heavy to hold the weight of the cookies. I found clay pots at Walmart for $.50 and paint them based on the occasion. You could also try the thrift stores for mugs, etc.
I use foam tucked down inside the holder and a piece of tissue paper. I use sandwich bags to wrap the cookie, and cut the fold top to give me more plastic to work with. Baggies are softer plastic than the goodie bags and easier to wrap around the stick and tie with curling ribbon.
I use bamboo skewer sticks - less expensive than the candy sticks. I don't like really thick cookies, so I roll about 1/4 to 3/8 inch thick and insert the skewer. I use two sticks to roll between to be sure the thickness is consistent. If part of the stick is showing in the back, I use a thin log of dough to patch the back, carefully roll it smooth, and be sure to place that side down on the baking sheet. Although if you are decorating the entire top, it wouldn't matter.
Once the cookies come out of the oven, I let them cool a bit before trying to move them. I use Toba Garretts icing and let dry, then use cake icing or royal to do the accents and let dry.
So far I have only done bouquets with six cookies, and for christmas did a combination cocoa cone and 4 cookies. Sorry didn't sell them, they were gifts or donated so I can't help with prices.
