You don't want to use galvanised wire to start with unless you want to burn the spring away while hardening it.
In fact you need
a) a suitable wire
b) the means for proper heat treatment

You can get ready to use spring wire and it needs to be wound up smaller than what you require as it coils back.
IMHO it is far too much hassle to make your own springs unless it really is the only option and as siad then I would go for spring wire instead.

Just to be clear here:
a) galvanised wire is usually not suited for spring use
b) it does not matter if you heat treat before or after as the galvanised wire will burn
If you need it galvanised than it will fail anyway.
The gal will break and crumble when the spring is in use as it is very brittle.
Better option would be to passify the wire with a phosphor coating or to simply use wire that is suited for your needs.
