​I am starting a consultancy firm for startups in early stages, what website host and plan is right for me?

Hello,

I am launching a consultancy firm in which I provide guidance for startups. The main necessities of my website would be a home page, a pricing/tier page, the ability to schedule meetings/a calendly link, and a portfolio page. Ideally reviews as well later down the line but that could possibly be blended in portfolio. I am also looking for the ability to have a custom email domain. What website should I use to both purchase and host my domain, as well as be able to assist with all of the above? I’m also curious if it would be possible to get a shopify store and pause it while also having a square or stripe link to still freely accept payment? Is this a bad idea? Curious on all thoughts for how to best set myself up without getting too costly. Thank you in advance for any and all advice!
