Hi Aaron-
There’s a couple major benefits for freelance designers like yourself that I’ll kind of summarize for you.
First, BoldGrid Inspirations gives you a huge head start when you’re making a new site by giving you 25+ themes with pre-designed starter content for 11 different types of industries, for websites ranging from a basic 3-page to 10-page content sets.
Just replace the starter content with your client’s copy and assets, and tweak what you need to rather than starting from scratch every time.
Inspirations also includes the Connect Search stock photography library directly in your WordPress Media library, so you can present your clients with full designs even if they haven’t given you much to work with.
Second, the Post and Page Builder’s block library does the same kind of thing, but on a section-based level. Find a block that’s close to what you need, and just tweak it for your needs rather than coming up with designs manually.
Finally, Cloud WordPress is a great way to develop new client sites and let them see a few different options to choose from, and you can use Total Upkeep to easily migrate your sites between your development environment, Cloud WordPress, and your client’s hosting service.
