http://www.kirkfarmers.co.uk/ they were willing to deliver to me in the south east from norfolk and I think they only deal with large bales very quick replies to e mails as well
We have a FANTASTIC supplier (he actually does both large and small bales, or a mix of both), very friendly, reliable, always makes sure you have a supply and I think his prices are reasonable!
I'll get his number off the board today at the yard and if you're still looking when I get back this evening I'll PM you with it!
