Disappointed by scam site myfreebtc.net, i want to build similar site which would actually pay.
i can handle HTML, some PHP and mysql. However i am stuck with the free roll page http://myfreebtc.net/home (after login). Basically i need code for page that will

1. Show coinhive captcha and a button which will be enabled after completion of captcha
2. Button click will verify captcha completion and generate a random number to be displayed below the bilitton. Minimum and maximum for the random number should be definable.
3. In place of coinhive captcha, a timer will start running.
4. After a defined time the captcha will again be displayed for completion again.

Any help will be appreciated. I can also pay for the code. Or if anyone want to partner in the site (no investment needed from partner), that may also be considered.

Regards.
