I think these are the people?
http://www.godminster.com/ I have never tried their cheese before, I might give it a go
Another thing to do would be to get in contact with artisan cheese producers and ask them questions about cheese making, as they may be able to help you. Maybe when you start to make cheddar you could alter the recipe slightly to make your own cheddar recipe. I use special starters for mine (my own secret recipe) as buffalo milk has a higher fat content, so we needed a special starter to enhance all the flavors of the milk into the cheese, all natural no artificial anything. Maybe you could buy some when I am making it again, to see what you think of it, we hope to get the units signed off before too long, so we should be making mozzarella and hopefully buffalo cheddar again too
I myself am going to be experimenting with making sheep's milk brie cheese, hopefully from my own two ewes I bought especially. Keep up the good work and I am sure all will turn out well. Another thing you could do is once you have mastered making cheddar you could smoke some, cold oak smoked cheddar is gorgeous. I have a friend who does it and it is phenomenal. Do keep us updated on how you get on
