Hi,
I can create a page in your wordpress site to have the calculator as in the excel. It would be helpful if you could provide the excel to understand its working better.
Pls PM me to discuss further details.
I have 4 years of front-end devlopment using HTML, CSS, JS, jQuery, Bootstrap and AngualarJS. I am proficient programmer in asp.net and php also. I can assure you that I will provide quality work in given time period without any issues. The final code will be delivered with comments and documentation.
Looking forward to work with you,
Kasi
