I am planning to open a new betting advisory service. It will be a site with registration, new members will register and when I add a new pick there will be information about active pick and members will receive it also on their emails. There will also be a monthly and overally statistics. I dont want to advertise other betting services here, but will give 2 links to such services and this will be the example of how I would like my site to be. These sitesarestandardpicks.com and rakasbets.com
As you can see, there are user panel, statistics, active picks and statistics are counting automatically, site admin is only posting a pick and settling it as won, lost or void. I would also the site to calculate automatically all stats.
Please tell me, is that all possible to achieve this using only free extensions to Drupal?
And if its possible, is it really hard to do or its medium level and will take couple of hours to achieve this?
Thank you in advance for reply, regards :-)
