Move the sales process forward – Landing Page/Form

I have clients visiting my page where I create content in my industry, and I want to start converting more to sales, as majority of sales come from a different platform and through direct phone calls (high value $). I would like to setup a landing page where this gives me a form with more of their info and gives me the ability to contact. Would be GREAT if this form can auto populate HubSpot. Does anyone have a recommendation?

Thanks for your help and recommendations! Have a great Sunday.
