Aquaponic Pricing

If I were to build an Aquaponics System for someone... a system ready to add fish and plants....the below spreadsheet would be the breakdown for a 2 waterfall, course with 3' deep 4'x5' irregular, stone lined pond, that is connected to a 4'x8' hydoponic vegetable platform.

This is the way that I would construct my final price.  But you wouldn't see this breakdown.

You would see a one page sheet that says....


Complete Aquaponic System with two waterfall course, 4'x5' Pond capable of keeping Koi four seasons and adjacent integrated hydroponic growing system.
$5,000.00.  Payment in full upon completion.

So for $5,000 you would be ready to relax to a soothing waterfall, watch your  fish, and harvest hydroponically grown plants and vegetables.

It hardly seems enough.
