Unless you have some freakishly unique physical characteristics (very tall/short, long/short arms, hunchback, etc.), I don't think you're an "idiot" for thinking of getting fit but I personally think it is "silly."
First, try an online static fitting tool like here: https://www.hirekogolf.com/get-fit-system . See what the outcome is. I'd wager that most people within a typical range of physical characteristics will be "fitted" for standard lengths, regular flex, standard lies, standard lofts and standard or midsize grips.
Next, go to Golfworks and look at the KE4 Max Paks (6-GW or 5-GW). If your online "fitting" suggests some variance from standard, they will custom build to your specifications and you will have a brand new set of customized irons which, the vast majority of online reviews, say are great for beginners as well as many better low handicap golfers. Your total cost will be less than $300 for the irons giving you plenty of budget left to consider hybrids, fairway woods and a driver. (You could also get a 4 AND 5 hybrid fully customized for around $150).
I do not believe a personal club fitting session or two and any OEM clubs will deliver for you any significantly better performance or outcome as you grow into the game. It will certainly and needlessly dent your wallet though.
