I am so excited, I have finally found a horse share!
After months of looking and meeting some right characters, I have found a beautiful 16h thoroughbred, with lovely owners.
He is 20, but not an old man yet, very strong but very responsive in the school, and I caught him first try with no hassle. 
We have discussed almost everything, from yard rules to feed routine, except for money. The owner said that she was looking for someone to give him the time and attention that she can't, with a little exercise a few days a week, and asked me how much I feel I should contribute money-wise. I offered £25 a week, but she said that was too much.
He is on full livery and is shod front and back, so how much do you think is reasonable contribution?
