Late 2017 iMac 4k

[ColG]

I am in England near Norwich. Can anybody recommend a company that will upgrade the memory from 8 gig to 32 gig in my above machine?

Thanks

Buy 2 8gb DIMMs and add them yourself.
That will give you 24gb.
Will that be enough?

If not, buy 2 16gb DIMMs and add them yourself.

This is child's play.
