This might not be exactly what you had in mind but I found at wal-mart, 2 years ago, natural body brushes for dry brushing for only 99 cents. I wrote a little note on personalized paper explaining the benefits and how-to of dry brushing and wrapped it in pretty floral paper. It made a great x-mas gift for about $3 and it had my name on it. I put the sticky label with my business on the wooden handle of the brush.
We have given goodie bags of chocolates, a $5 gift card and a customized lip balm from http://www.lipbalmexpress.com. Cients love the taste and your names is printed on them !
