Need Reassurance for $40k budget

I live in Denver, CO & have been told will be getting engaged in the next 2-3 months. I’m starting to look at venue options to get an idea of what to expect for about 150 guests and ideally a 6-8 month engagement. My partner and I can max do a $40k budget for everything just between the 2 of us. We aren’t yet sure if parents on either side will be contributing (won’t have that conversation until after engagement, but we aren’t counting on them to contribute). I’m starting to feel overwhelmed with how “average” that budget is and how little it actually covers. I’m in between DIYing everything and going the all inclusive route to cut down on stress & Individual costs.

Posting here to get some reassurance that this budget is doable and will result in a pleasant guest experience. I don’t care about bells and whistles or any elaborate extras but do definitely care about the authenticity of the event and making sure it feels like us! If anyone has any recommendations, please send them my way!

Thanks in advance
