If this is your first season and you're struggling I would suggest this;
Start a game only looking for 5f horses.
Trial everything you can get your hands on in a season at 5f.
send the very best male, and best few fillies to stud.
do this for a few quick seasons, shouldn't take too long.
Once you have a breeding stock (only using the best male you have in your CK each season), keep going in the same manner.
Trial the ones you find (game horses) against your current lot, once a male is close to, or bearting them, then use him as your first breeder.
Making sure your first male is good is a key to getting a good line quickly.
Once you have that good male breed him with as many females as possible that trial well. Only trial the females with other females for now and use the best.
Keep doing this and you will get a decent bloodline going with your males quickly for 5f. After a while you will notice that a few horses actually start to need 6f. Trial these against your current lot at 6f and anythng beating them, use as a start for 6f bloodline.
This will continue through the distances. IMO this is the quickest way to get horses ready for the league, and get a few good runs from them, not challenging at the very top, but will possibly pick up a few lower rated H'capps.
This isn't what I would do if I had more time, but I think it may help you if you only have about a month to get going. I think you will notice your horses improve pretty quickly.
Hope something in there makes sense, and helps.
If you want any advice I will be happy to help out on msn if you're on it.
