Upgrading Breaker Panel on a renter

[Chris Lo]

I need a rough estimate on this job. I'm renting a Townhouse size of 1000 sq/ft until i get a house in 1.5-2 years.

i currently use ~2800W on 110V and ~1000W on 240V running 24/7. My main breaker has only 50A so i'm planning to upgrade my 1900~1950s panel (Townhouse in michigan).

Going down the road, i'd like to have max of 7600W running 24/7. Preferably on 240v if that makes this panel upgrade cheaper. ( machine running ~2800W on 110V can be moved to 240v) (i can have the outlets right next to the panel since the machines are close enough to the panel.)

Reddit people are saying this job will cost upwards of 10K$ since the current wires need to be upgraded.

On BP, i'm seeing people say something like this would cost 1-3k$. 

How much am i looking to pay for something like this? 

I've contacted a lot of electric companies and looking to call more for availability. If you work for a company in michigan and will to do the job then let me know.
