What is the best website for wholesale hanging pots (For plants)?

My mum sells gardening gloves at a local community market, as part of her display she hangs up these "Hanging Baskets" that have about seven large holes cut out so you can put about 7 or 8 plants in them. my mum can't remember where she got them or how much they were. and because they are a part of her display she keeps getting enquiries about how much they are to buy! If anyone can send me a link or help me out it would be much appreciated! thanks :D
