Dear Friend,
With 2+ year experience in Codeigniter, JQuery, CSS, Bootstrap 3, and various JQuery plugins, delivered many projects in short period of time.
If you give a chance to prove on Freelancer.com, I assure you, that will give better quality.
I do add server side verification to prevent from hijack, that many don't know or only show.
CodeIgniter itself is having security modules like XSS, it adds extra layer of security.
As you described, all the things, which are mostly common things in my day to day projects, can be completed with 3 days.
Before starting, I can show you a demo of it also.
Regards
