Hi There.
Thanks for posting the project here on Freelancer.com
I'm Santosh Singh and I've over 8 years of experience in Web development. As per my understanding you would like to develop a plugin which can simple post videos from your website to the Facebook using Share button, I can develop the same. Let me know the questions you have.
I've placed a placeholder bid which I'll change after discussing final requirements with you.
100% quality work is assured.
Looking forward to working with you.
Thank You.
Regards,
Santosh M.
