Branding and Marketing a brand new product/service solution for hiring industry.

Looking to advertise a completely new type of product/service that's highly desired in the hiring industry but nothing like it exists. We already have a small number of clients using this service. We have a logo designed and a lot of literature we've written, but what we need is to look professional and credible. Our product/service is highly complex AI and requires lots of consultation to implement with a company. It's B2B (business to business) solution.
