An alternative is to install a breaker-box yourself. You can get
everything you need at the box store and, with an afternoon's* work,
you should be able to swap out the fuse box for a 200 Amp service.

Should cost about $300.

Around here, as I suspect is the case in most areas, that would mean having
the utility come out to disconnect main power and then come back out to
reconnect it, and they won't reconnect it without a licensed electrician
signing off on the work.

Those three charges would need to be added to your $300 estimate.
