Second guessing my original decision about making my first short film..

..the way I wanted to. So to explain quickly, I have a producer with other short film credits who is willing to be onboard for this short. They love the script and understandably see it as a credit worth having so they're willing to line produce this for free. However, my original plan was to hire a 1st AC, a gaffer, a sound recordist and that's about it, other than the 4 actors. It's a short based in one location only, one specific type of small home I will need as a location that I am looking for. The budget that this person came back to me with, is more than $10,000.

Before I say anything else, I want to mention I am funding this out of my pocket entirely and that's way out of my budget. I also want to mention I am the entire post-production on this (even with color, I know very specifically what I am doing, working with braw and colour-managing my footage from braw > dwg > rec709 and then tweaking things for adjustments in successive nodes). I will be editing this and designing the sound bed using professional sound libraries I have collected over the years by paying out of pocket for those licenses too. I was going to communicate to the gaffer the look I want based on a mood board and lighting ratios and ambient fill levels motivated by practicals I will place in the room. The list that this producer gave me now includes everything from AD to hair and makeup, 4 figures for marketing, etc. I understand the urge to have more crew but someone needs to pay for all this and I am trying to not have unpaid people with me doing any work on this.

So I wanted to ask people here who have done it, is it worth doing this 11-page, one location script with the crew I originally had on mind or do I need 2 or 3 times the amount of people, ballooning this to 5 figures in budget? Of course if other people pitch in money, I lose some creative control, that's not what I want.
