I am looking for some gold buttons for my PC. Something just like the standard square silver ones that are already on it.

I've been searching the web and the only ones I can find are these:

They are 14K gold and $295 each! Very nice, but gold plated and much cheaper will do me nicely for now at least. Does anyone know where I can find some square gold buttons at a reasonable price please?

Also, I am thinking of having small eyelets put in my jacket so I can have the buttons attached with split pins. Then I can interchange the gold buttons for silver ones and also remove them for dry cleaning. I am hoping my local tailor can do the job. Has anyone done this? Is it indeed practical?

Thanks in advance for your advice.
