Hi, I can put you in direct contact with the company and owners who can support you with this further. They might be able to offer a discount if you mention The SEND Advisory Team and SENCo Forum – let me chase it up as it was something they mentioned when I met with them. They also do fantastic demonstrations that are usually free.
If you are interested, drop me an email at kate@sendavisoryteam.co.uk and I can see what I can do.
