sport bet website/app

Hello, I would like to propose a website/app for a french tipster that has his own community in the french market but i'm not sure if your solution is adapted. Just for you to know: the guy wants to sell them through a website a paid plan with a monthly/3months/6 months paid plan and then a monthyl subscription. all members could have the possibility to test during the first month only paying 1€. These VIP subscribers will have access to premium services. the premium services will be the folowing : - between 4 and 15 betting tips per week - a live window chat during certain games where the tipster will invite members to bet during the game and to interact with him - A personal bankroll to allow members to monitor their sport betting performance (based on their own bets, whatever the bets were suggested by this tipster or not). Once this bankroll is feed, the member could see some charts to better analyse his performance. - The tipster bankroll (with charts too) based only on the forecasts given by the tipster to the members. please note that this charts will be also displayed to non-members to prove the service quality. - Multi bookmakers comparison of odds - Other relevants tools that could help the member in their betting management Please note that the business model will be also based on affiliation, i was wondering working with gambling affiliation. Also, i would need you to tell me what would be the technology used for the website : wordpress ? If not, a back end office allowing non techy guys to feed the content would be necessary. also, would the app content will be automatically updated once the website is updated ?
