It is preferred that you come to the website project with your own pictures to use. Depending on your business this could be easy or it could be difficult. It is always better if you supply photos of your team, you on the job. Original photos and something unique to you will always stand out. That being said, for new businesses, photos may just not be an option to start. In such cases I will refer you to a stock photography site such as unsplash.com or depositphotos.com where you can find photos that represent what you do. Over time, as your business grows and you are able to take more pictures, we can replace the stock photos on the site.
