Need expert in AI Implementation To Build and Agentic Ai agency

I am looking to start a managed services AI business consulting agency where we create AI products, automations, agents, etc., for small to mid-sized businesses and charge/bill for these deliverables and we also manage them for them for a monthly fee (monthly retainer). I'm looking for an AI implementation expert to hire long term to help me build the agency and deliver the results. It's important to understand that I want to approach each client with with a comprehensive solution whereby we build a knowledge graph for them, a brain, so when we start implementing Ai systems they are all interconnected and will not break. At the same time we need to develop the same knowledge graph, brain, for the agency so it is fed by all the Brains we create for our clients and all the systems and solutions we implement so as we grow, we do not have to start from zero but have the knowledge graph as our foundation to feed from. If you have read this put "Barcelona" in your offer.
