At a high level what elements are required for text UI in VR?

Hi everyone, Im guiding a team to build a VR archviz app and being not technical (I'm a project manager) I need some help to understand the UI workflow. The outcome should be that when the user hovers over a model they see a text animation spawn from the model. The animation is coded, my question is about the visual aspect of the text; what is the requirement for the graphic text elements? does this have to be created in unity or can it be created in photoshop or similar and applied to a unity model? How long would it take for a basic text graphic with a "outer glow" style effect

I'm not technical just trying for better insight into my team's needs. Thanks for your help
