Hi,
I am able to create you a website with formulas and calculations, but I would need more details in order to give you a price and a time frame.
I have 5 years of expertise in this field and I consider every project is important, that's why I will offer you my full support during the process.
A prove of my strong skills in Website Development and Design are the reviews from my profile.
I am looking forward for your reply in order to discuss more details.
Thanks for your time.
