Hi,
I have worked on bet365 on maybe more than 100 projects, I know all the intricacies of bet365.
Depending on the sports/markets you want, you will need probably some VPS running all day long to scrap the odds along with the links.
The app I will code will be responsible for pulling the data from bet365, all what needed so you can insert that data into your website and have the odds link directly to bet365 market, or even the betslip.
The speed of refresh will depend on how many VPS you can have. especially if you need all sports/markets.
The quote doesnt include the html on your site, the app will insert the data into a database and it is up to you to refresh your website with that data. or better yet, we use some kind of tcp communication, you your website is updated automatically from the feed I supply.
Also the quote doesnt include all sports, here only 3 sports for the budget.
Drop me a line if you want to discuss more.
