SeaStock investor deck

I am looking for an experienced freelancer to create an investor deck for my company, SeaStock. This deck will be in PowerPoint format and the primary purpose is to attract potential investors. Financial data will not be included so the focus should be on other information such as our mission, vision, team, progress, and projected goals. The deck should be visually appealing, clear, concise, and provide a comprehensive overview of my company for potential investors. We have had it designed but it looks amateurish. Needs better imagery - ie not the cows burping - it needs to look scientific and backed by concrete data.
