Need a Cleaning Services Cost Calculator With Instant Quote Request

We run a residential and office cleaning company and want to stop quoting jobs manually over the phone or in messengers. Right now every new inquiry means a back-and-forth: the client describes the space, we ask follow-up questions, someone does rough math in a spreadsheet, and only then do we send back a price. It is slow, it is inconsistent between managers, and we lose leads who expected an instant number on the spot.

We need a calculator widget for our website where a visitor selects the type of cleaning — general deep cleaning, regular maintenance cleaning, or post-renovation cleaning — enters the area of the property in square meters, and optionally flags extras like windows, upholstery, or a kitchen with heavy grease. Based on that input the tool should instantly show an estimated price and the expected time on site, using rates and coefficients we will provide for each cleaning type and property category such as apartment, house, or office.

The calculator should end with a short request form — name, phone, preferred date — so a ready-to-book visitor can submit a callout request in one click without leaving the page, and we get a notification with the calculated price attached.

What we are looking for:
— a clean, mobile-friendly widget that fits into an existing site
— editable pricing logic (rates, multipliers, minimum order) without touching code
— validation on required fields and reasonable min/max area limits
— a simple admin-side way to update coefficients as our price list changes
