Bonsai nurserys

Hi all i'm new to this news group. Anyway i was wondering if anyone could
point me to a decent bonsai nursery near birmingham in the uk. I have a
nursery near me but it is terrible i have bought several trees from there
but all have had to be nursed back to health over a long period of time and
several died, and these were the best specimens there! So if anyone could
point me to a nursery near birmingham i would really appreiciate it thank
you.
