Create webscraper & GUI for business buying websites

I would like a website scraper that I can use to scrape the following websites for business listings.

www.bizbuysell.com
www.bizquest.com
www.businessforsale.com
www.bizbroker.net
www.bizben.com
www.midstreet.com/businesses-for-sale
www.tworld.com/buy-a-business/

I would need a .csv output or ideally a Google Sheets output and a GUI so that I can use it once a month to update my records.

I would like to check each state in the USA and scrape slowly over a matter of hours so I dont get banned. I would like to have the option of searching several states at once or one at a time.

I will require the following information to be scraped if it appears on the website:

-Listing URL
-Listing name
-Listing location
-Listing description
-Asking price
-Cash flow
-Revenue
-EBITDA
-FF&E
-Inventory
-Rent
-Established
-Inventory
-Real estate
-Building SF
-Lease expiration
-Employees
-Furniture, Fixtures, & Equipment (FF&E)
-Facilities
-Competition
-Growth & expansion
-Support & training
-Reason for selling
-Business website

I would like this to have a simple GUI that I can select a few parameters as follows:

-Selling price range
-State
-Revenue
-Cashflow

Could you do this?

How long would it take?

How much would it cost?
