I got mine from our local Speedy Hire. Made friends with the bloke on the desk (gave him a few bags of veg) and I helped myself to the old and cracked boards behind their depot. Messy job, had to get them myself, load the car (some were 4m long lol) the get them home and clean them up before cutting them to size. Took the best part of a year. I enquired of HSS hire shop, they just quoted 'elf and safety to me.
