Hi need a Core PHP developer to make at least 80% changes to a existing calculator on our website. We need to change the design on of the front end as well as the way the results are displayed. Results should be given in a pop up screen and the user must have the ability to email the completed calculations to him / her self in high resolution PDF format. After the user has emailed the calculations to himself he should be prompted to refer the calculator to a friend, with the ability to enter a friend`s email address, the referred person should then receive a email notifying him that the person who did the referral has referred him to the calculator. Keep in mind that design work is also needed on the front end, we need a better looking version than the current version. Project also needs to be completed within 3 days.
This is the link to the calculator that we need to redo: [url removed, login to view]
