Powered Soil Sample Probe

[dig]

'm considering manufacturing a gas-powered soil sampling probe to be used with atv/utv's. I'm curious what the market values a machine that can do 80-90 acres/hour, is self-contained, and does not require the operator to leave his seat at? It sounds ridiculous, but the ROI mark to make it feasible looks to me like it'd be between $4000 and $5000 retail. I'm just looking for some feedback here. Thanks!
