Have you checked out any online directories or review sites like Angie's List or Yelp? Those can be great sources for finding local contractors and reading reviews from previous customers. In addition to using online directories and asking for recommendations, you may also want to consider conducting pre-employment screenings on potential candidates, this can now be done using public
web services. This can help you ensure that the contractor you hire is licensed and has a good track record of completing projects successfully. You can also look up the contractor's license and check for any complaints or disciplinary actions on file with your state's licensing board. By doing your due diligence ahead of time, you can increase your chances of finding a reliable and qualified concrete contractor for your project.
