Hi,
I read your requirement, you stated that you need some one should take care of the development. For your knowledge I would like to explain about my experience here, for more than a decade I am developing and delivering applications using PHP, JS, MYSQL with CI, YII and Open Cart. I am certified professional on PHP and MYSQL, even in the freelancer.com site, in the skill tests I have cleared most of the technical exams with 90% and above.
Thanks
Paul.
