Cost to re-wire 550 sq ft cabin

Hello everyone, I have a 550 square foot cabin on a Gulf Island in British Columbia, Canada.

It was built well but the problem is that as far as wiring goes it wasn’t built up to code at all and it’s not actually connected to the power lines. The previous owner just got power by plugging into the neighbours house for $20 here and there. It worked fine because the only real power draw is a fridge, other than that just some light bulbs.

I want to get the place hooked up to the municipal power grid but I’m guessing that the place will have to be re-wired professionally.

Any idea what sort of cost I would be looking at? If it helps, there are maybe 6 household outlets and 4 wall switches in the whole place. The place is slightly raised off the ground so an electrician would be able to crawl under the whole thing if that does anything. There are no lighting fixtures or anything actually attached to the place, the light is just from standing lamps.

Thanks in advance for any rough estimates.
