Advice for starting web hosting

Hello everyone, I have a question... Currently, I am running an SEO agency, I also provide custom website design and development services, but I want to extend my list of services by adding hosting services. So, the question is should I add web hosting services to my existing website? Or should I start a new separate website for this purpose? You guys are professional, so you can give a piece of good advice. That's why I'm asking you... You can check my current website here: https://thedesignsfirm.com/. Review it and answer, please. Thanks!
