If you go into 's' on my website and you will find a typical show schedule which you can adapt to your own situation.
Regarding judges I agree with Robert I think you will be very lucky if you can find a judge now,particularly if your show is on a Saturday or Sunday.
Quite often the judge is rebooked immediately after the show for the following year.
Each year there is less of them about because no one is taking up from where older judges have left of thus creating a shortage of judges.
In our group five of our national judges have died in the last two years and I only know of one who has qualified to judge since,hence the shortage.
This is not just happening in our area it is happening nationally!
As someone else has said try and find a good grower in your area to judge for you. As Laurie said,they don,t all charge.
Quite often they will settle for the price of a couple of gallons of petrol.
Best of luck with your venture!
