I would strongly encourage you to not do hourly payments and I’ll explain why:
When you’re paid by the hour, you’re punished for being good at your job.
As you get better and more experienced you’re going to do things more quickly than someone with less experience.
eg. I can write a blog post 10 times as fast as my VA because I’ve been doing it so long.
Imagine, Lewis Hamilton, the F1 driver, do you think he gets paid more or less if he finishes the race faster?
Always switch to value based pricing for design services.
