Build a Website like betfair, bet365

i need a betting website, one EXACTLY like betfair. We are NOT looking to create a WEBSITE” of betfair, but a similar website. NOW TO A MORE IN-DEPTH PART OF THE WEBSITE TO BE DEVELOPED. We want our website should mimic betfair markets as every price change should also be reflected on our website. If a bet is unmatched on our account with the original betfair, it should also display here on the newly developed website. Also our website should have custom pricing options. This means that such website created should allow for us “the admin” to adjust our pricing in relation to betfairs’. Please view example below:- The following example shows our website with a command to subtract from every BACK price on the betfair market to be displayed on our website AND a command to also to every LAY price on the market. 1. BETFAIR BACK & LAY MARKET (SAME MARKET) 2. OUR WEBSITE BACK & LAY MARKET (SAME MARKET) Thanks!
