Build responsive website for mental health private practice

Description

I need a website built for mental health private practice. I am open to wordpress vs squarespace but would prefer wordpress due to what seems to be better SEO. This website needs to be mobile-friendly. I would like to be taught how to make updates to information on the website if minor changes are needed in the future. I am fairly direct in my communication. I make decisions quickly and will respect your input/feedback as the expert.
