For cots, what I've bought for my 3 kiddos are these: Regalo My Cot Travel Bed. The kids seem to like them enough! http://www.walmart.com/ip/Regalo-My-...el-Bed/4433186

I buy these in the US (and they're $26). I believe that Toys R Us now carries them (or will be), but are about $40. http://www.toysrus.ca/product/index....eeEnabled=true

I just ask parents to provide me with a crib mattress protector in case of any accidents, as well as any bedding.

Otherwise you can go to a daycare store and buy the cots that centers use. Ie: http://www.avronforkids.com/products...27+Wx5%27%27+H Just make sure that if you go this route, to make sure you're getting the standard size, and NOT the toddler size.
