Looking for lesser known UK horseracing online bookies

[Hareeba!]

None of the leading bookies will accept any business from me on UK horses.
I'm hoping to find one or two bookies who will:
a) accept Australian clients
b) offer Best Odds Guarantee
c) take a reasonable sized wager and not impose absurd limits after a few wins
d) accept deposits via Skrill

Hopefully someone here can give me some guidance?
