Hi,
This looks like the job for me :-)
I've done it many times before, I'll do it with PHPProtect and it would most probably take less than 2 days to finish.
I might add that I'm a LEMP (Linux/NginX/MySQL+MongoDB/PHP) stack developer with +15 years of experience in PHP, working on projects of different sizes.
I can start on your project immediately and let me know if you want to discuss anything further with me.
Thanks.
