One idea is to map-out your proposed Product Value Ladder. This is a strategy map read left-to-right that progresses from Free or Low-ticket product\offer components which lead to high-ticket offerings. All these offers can be thought of as a strategic package all targeting one Product (your new Product). Then start testing your new product out - develop an offer from this Ladder that is compelling and attractive to your target audience. For the testing phase, it's best to do a combo of direct one-on-one meetings to gauge interest, ask for referrals and get feedback on how the offer resonates with them. For online presence of this offer, best for the CTA button to redirect to a pre-launch interest form to gather (build your list) their info so if you decide to launch this product offer - you have some Yes's you can directly target.
