Building a Jockey Challenge Program Calculator for Gambling -- 2

I would like to get created a Jockey Challenge Calculator program. Gambling agents in Australia bet on jockey challenges and a jockey challenge is basically a bet type and who will ride the most winners. The jockeys get the following points. 1st 3 points / 2nd 2 points / 3rd 1 point who ever gets the most points after the last race wins. The pricing works for a jockey by how many rides the jockey has and what price there horse is paying to win the race so the price of the horse will need to be scraped from the website below.

Below is the website that has all the information need to get the jockeys from the meetings as everyday new meetings are added. Each state in Australia has different times they Final Scratchings are released and rider changes can be changed at any time so need the program/calculator to always update from this site. Who ever accepts this i can send them videos of a program i have found from a mate to get an idea on how it works. Only problem is i don't know how the last part is calculatored to get the final price. The horse meetings and jockeys are found at this website below
