Research Marine Contractors in Florida and Create Excel List

I need someone to create an Excel list of all active Marine Contractors and Dock Builders in Florida. My goal is to create a list of all marine contractors that build / install boat docks within the State of Florida. My company builds boat docks and we need this information to market our products to these contractors. The information should be accurately entered to an Excel spreadsheet. It should include:

Company Name
Contact Names

Email address
Cell Phone
Company Phone
Street Address
City
State
Zip Code
Website

Some methods to find the information could include:
1. Google searches such as marine contractor, marine construction or dock builder for each medium and large city in Florida.
2. Association directories such as ---------- and others.
3. Web scraping or other techniques.
4. Any other efficient methods to collect this information.

When complete, there should be hundreds of companies listed.
