Ask HN: How do you approach design for your products/SaaS/Websites?

I'm looking to launch a new service. Previously I've taken a theme and customized it but this time, to try and save some time and delegate I thought I would try hiring a designer. Expected costs for a simple (5 page) website are around $1,500 without implementation - purely a Figma file at the end of it.

How do you approach UI/UX/Design? Do you hire someone, customize a template or something else?
