Form calculater

I’m looking for a developer to build a quote calculator for my decorating business and integrate it into my website.

The calculator needs to allow customers to:

- Enter room dimensions (length, width, height)
- Select how many rooms
- Choose options such as:
- Doors (number of doors)
- Door casings
- Skirting boards
- Ceilings

Important requirement:
The pricing must change based on condition using conditional logic. For example:

- If “previously painted” is selected → standard rate
- If “bare wood” is selected → higher rate

The form should:

- Automatically calculate an estimated price range (not a fixed price)
- Display something like “Estimated cost: £X – £X”
- Include a disclaimer that the final quote may vary after inspection
- Send the enquiry details to my email

My website is built on: [squarespace]

I want something clean, simple, and mobile-friendly.

Please only apply if you have experience building:

- Quote calculators
- Form calculations
- Conditional logic forms

If possible, include examples of similar work.
