Here are my thoughts:

*Steel wool
Easy to get, but make sure you don't get one with soap, like the
common Svinto brand, since you want to keep the board clean.

*Isopropanol
Should be pretty easy to get. I imagine a gas station might carry it
or maybe a tool shop or painter's shop.

*Ferric chloride
I doubt you can get it easily in small quantities for an affordable
price. It might be possible to ask a painter's shop to buy some from a
distributor, or contact a distributor directly.
It's also worth noting that you need a well ventilated place when
working with it since it may emit hydrochloric acid when working with
it.

*Acetone
Also easy to get and any well assorted Coop/Ica supermarket should
have it. You should probably avoid the type with oil in it, commonly
used for removing nail polish. Requires good ventilation as well.

*Liquid tin
I don't know exactly what liquid tin is or how/where to get it. It's
obviously a chemical that deposits tin on top of the copper. Might be
as simple as tin chloride. If so, you could make your own pretty
easily by dissolving tin in hydrochloric acid to make tin chloride. At
any rate, this step is not strictly required, especially not if using
flux when soldering. (Which will increase solderability.)

What was not mentioned in the video is drilling. For drilling you need
a good drill, preferably a "perlarborr" (don't know what that is
called in English...)
This kind of thing:

It's not impossible to solder hole mount components as surface mount
but it requires skill, and preferably that you take that into
consideration when designing the board.
