Just a quick thought: depending on how adventurous you feel, you might consider buying ready-made pizza dough from the supermarket, and start with that.

If you like your pizza, the next iteration would be to also make the dough yourself. Expect several iterations / attempts until you can make it well and reproducible, and get a good feel for how much you need.

The first few batches of pizza dough I made were not very good :-).
