Build a Google Form with integration of Quotation Calculator

Hi, I am in the field of accounting, taxation for UK. My core services are Bookkeeping, VAT, Year end Annual Accounts and tax returns. Each services has multiple criteria to decide the charges from client.

I want a calculator link, by which a customer can fill their work details either in the mcq type or such other type and at the end after submission he got a mail for the quotation in the proforma.
