Create a custom CRM with client portal -- 2

I'm looking to create a custom CRM with a client portal, and need some help getting started. The CRM should include features like contact management, sales pipeline tracking, and task management. The client portal should be customizable, with access to staff details, invoice, quote acceptance, and event notes. On top of this, we need the CRM to have the ability to connect to certain integrations or APIs. If you think you can help make this project a reality, please get in touch!
