PhP, JavaScript, Ajax Web Developer Needed(repost)

I would like a site coded similiar to [[login to view URL]][1] if you click on "demo" you will a calendar appear, I need this coded and the other tabs like "configure" with those options, adding/removing users, etc. and the ROI calculator which you can plug-in numbers and tells you the ROI. The calendar needs to be user friendly as the people using it are not going to all be computer savvy. Calendar should use ajax, and it will need to be implemented with Twilio to send voice, text, and e-mail messages at the scheduled time and date. All the functions you see on that site, will need to be implemented in this site the only thing is the design and basic html pages will be done by another web designer. You will need to implement the ROI and Calendar into the designed website that I provide. It should be done in about 2-3 days from today. The site also needs to implement billing with [login to view URL] merchant account. I would like the site to be completed within 2 weeks, no later than 4 weeks.
