Well things like 'shoeig' require farriers which the trainer sorts out and they will just give you a monthly/weekly/daily fee for everything included - the additionals all come under one bill. I've heard good things about John McArdle at Mornington from friends that have horses with him and I personally love the way he goes about it (just my opinion.)
Just remember that there are 2 givens in racehorse ownership, and bills are one
Good luck mate.
