I have a business idea that I need a website for. It is not online selling but rather service based with a members only portal. When someone visits the site and if they click on Contact Us or Apply Now they become a potential lead and the lead can be purchased by members only through the portal. If possible I am looking to make the system of purchasing the leads automatic and I need Contact Us and Apply Now application form. I assume the biggest section of the website will be the portal. Is this someone Shopify can manage?
