HubSpot Implementation and Onboarding

We currently have a simple PipeDrive setup, about 200 companies, 1-2K contacts, 100 leads. We are small, will have approx. 5 users. We are looking for someone to help us setup HubSpot correctly, train us and to build a long term relationship to support us as we become more advanced users. Help us to import the contact information (don’t need the emails) from PD. Integrate HubSpot into our environment, Google Workspace, Slack, Asana. Setup custom reports (our sales include a fixed cost setup component and a multi months/year subscription component). In PD we have never successfully been able to forecast our revenue by month over multiple years. Initial marketing is B2B, with small, targeted LinkedIn and email campaigns. We need a standard simple workflow. Service, we want to start with simple ticket system, to track, manage user requests, about 10-20 per day, not much. What do you suggest is the best way to work together, what is your overall cost estimate?
