Originally I create this shiny interface that takes in a parameter \"company id\" and \"date\", but here we have a problem: most people dont know the companies we work with

Sure, just use a textInput for the search string, and use renderUI/uiOutput to make a dynamic selectInput. Then the rest of your code can depend on the selectInput's value. (Make sure to check for NULL or whatever when reading the selectInput value, because it will start out with no value.)
