Hmm.... for the labels, here's a good site to order some: http://www.namemaker.com/ but you can really just google "sewing business labels" or something in that context and a bunch of good links will come up where you can order labels from. Good luck with everything!
Wow those are really cute! I love the red polka dot fabric. As for price, I would probably pay about $15-$20 for one, pretty much what everyone else said. But it really depends on the cost of materials and how much work/time it takes you to make them.
