Mining Query

Hypothetically if I had access to free electricity in the UK little IT support from a business perspective:

1. Could the miner be traced back to me

2. Would it be completely obvious in a large warehouse plenty of places to locate it via wifi

3.what setup be like ie cost and initial set up for a novice

1. Would it be profitable im talking a few grand a year nothing crazy.

5.Where would you even start.

Thanks
