Hello,
I am full time freelancer.
I have extensive experience in building web applications.
I have read all your requirements and understand them well.
I have consistently delivered projects on time and under budget.
In order to help you in making your decision , I can break the tasks into two points
1) POC - I can provide you the proof of concept which will serve the key functionality of your website. Can provide you the wireframes based on your requirement .
2) Full fledged project .
Thanks
