Rate Calculator to be developed for wordpress website

We need a calculator developed for a WordPress website. Needs to calculate Title Insurance rates. Please see [login to view URL] for an example of a similiar calculator. 1. We need to be able to easily update the rate for Title insurance as well as costs for Loan and Owner Endorsements. a. Title insurance rates will be provided in an excel spreadsheet, and updates should be able to be handled by uploading a new excel spreadsheet. 2. Our calculator is for one specific State and a few counties within that state that all have the same title rates, so there is just one set of title rates. Title rate is calculated based on price (purchase price for a purchase and refinance amount for a refinance). 3. There is only one underwriter rate. 4. There are only two transaction types: a. Property purchase with and without financing b. Refinance Loans only (replaces existing financing) 5. Purchase amount/Value needs to be a fill in cell (like in example calculator) 6. There will be only Loan #1 and Loan #2 (not 5 loans as in example calculator), both need to be a fill-in cell (like in example calculator) 7. There is only "Residential" as a property type 8. The list of Endorsements on the backend, rates need to be editable. 9. Final summary needs to be printer friendly 10. Each screen of calculator, needs to have an "edit quote" button that allows visitor to edit previous entries. Ideally, calculator will be a wordpress plug in, but we are willing to consider other options as long as calculator can look like it is on the website and is easy to update when rates or costs change. We want to be sure this project is completed quickly and smoothly, so with proposal, please include a timeline. We will also expect daily updates on progress.
