Consult and provide advice only on the best Google Cloud Platform products and tools to use for a prototype of a product search autocomplete feature

I need to produce a working prototype using Google Cloud Platform that shows a web page where you have a text input field and as you type it searches through a database of products and auto-completes as you type. Just like when you start searching for a product on the [login to view URL] website, as you type into the search box, the search results start to appear below the search box, and the results get narrowed down the more characters you type. I don't actually want the solution coded for me, I'm just wanting to pay to talk to someone who is very knowledgeable in Google Cloud Platform and could advise me on the pros and cons of using the various GCP products/tools for this requirement.
