Canva vs capcut video editing pro work?

What is the fundamental difference between Canva and CapCut for professional video editing? My client specifically wants CapCut video editing, but my laptop lacks the necessary resources and capabilities. Is it worth investing in a high-performance laptop for video editing, costing at least $2,000? Additionally, after making this investment, what is the minimum amount I should charge per video to ensure a reasonable return on investment?
