Hi Kasim,
Your project looks very interesting and fun, and I would love the opportunity to help you! I have over 13 years of experience creating beautiful automated Excel dashboards and reports with calculators just like your file attached, and from your project description I am thinking I could create you a really nice, professional, fully functioning calculator in a relatively quick period of time. (Thinking end of day Monday)
We can use any type of logo the Client requires as well as the color scheme of the calculator itself.
I have a few portfolio items on my profile here if you would like to see some of my previous work.
Thanks either way, and best of luck!
Shaun
