Need help setting up a small business website in Castleisland

I'm starting a local craft business in Castleisland and need assistance getting a simple website up and running. I have the domain registered and some content ready, but I need help with the setup, choosing a platform (like WordPress or Squarespace), and basic design to make it look professional. Guidance on making it mobile-friendly and easy for me to update myself afterwards would be great. I'm flexible on timing but would like to get it sorted within the next couple of weeks.
