I've recently launched a content store, where I will sell various libs and recordings, on my site (http://www.samueljustice.net/content-store/).
I only have 3 libs up so far (one is free, some camera foley of a 1950's Kershaw camera). The other two are ambiences libraries, including a collection of English South Downs ambients (soundcloud preview at the bottom of this page).
I also have a few more in the works at the moment, including an alarms library from various exterior perspectives which I hope will be useful.
Please take a look around and let me know what you think!
