Buyer contacts for Retail chain 20 to 100 stores?

Hi Guys,
So dad's in the manufactureing business, Basically the stuff is designed in Canada, but made in China. The packaging is also designed by canadians as well. The stuff then gets shipped directly to the retailer's from the factory in China. I guess you can call him a wholesaler or sorts. I was wondering where I could get a good lists of Retail chain with 20 to 100 stores? Preferably with the contacts of the store's buyers too.

Behalf or my Dad, thanks!

One idea though, assuming that the product cost is low given it's produced in China, eBay would be great, also if you get some time put up what your dad is bringing in (product wise), I know there are a few people on RFD, including myself, looking into wholesalers, especially electronics
