I missed the "without filtration" so with that in mind then maybe yes but probably not. Around here the pool company would supply the hole, rebar, shotcrete and electrical. For a pond that size without the hole $500.00 to $1500,00 so we'll say $1000,00 that leaves $34,000.
The bid from the pool company would be $20,000 to $25,000 with the price of conctrete today at over $100,00/cu yd. Say $22.500. That leaves $11,500.
Approximately 800 sq ft of polyurea at $10.00/sq ft is $8,000 depending on prep. Now we're down to $3,500.
Two bottom drains, two skimmers and two midwater drains approximately $1,150.00.
TPR's how many? Say 6 depending on type $150.00 to $400.00. The type used will also have an impact on the add on pricing from the polyurea sprayer. Some they charge to deal with and some they don't. Now we're about $2000.00 away.
Who's doing the plumbing and layout? There is labor there and some shotcrete applicators won't shoot over anything that's not installed by a licensed "pool" plumber. If not you can do it yourself or hire someone who knows pond plumbing to do it. Pick that expense yourself.
On top of that any surface coating requires prep. The shotcrete can only be finnished to a point and all the detail finnishing must be done by someone. This can be labor intensive if not handled properly and is still another expense and will effect the price of the poly.
Who's managing the project, in charge of the layout and making sure each person on the job is doing it correctly. If it's you you'll need to know about all of those trades yourself so you end up with a pond and not a pool or spa. There might be an expense there.
If it's permitted by the local "powers that be" you have to make them happy along the way to get signed off and all they have to go by are pool specs so you need someone there that can handle them.
It would be very close but handing it over to a professional who has to make a living along the way it would be tough. If you were going to handle all the subs yourself and felt you could manage all the details it might be possible but the question was by a "professional".
The "hole" is the least expensive part of the project.
