Wood branding - has anyone had experience?

Hey all, I'm looking into getting some small wooden discs (imagine wooden trolley pounds) branded with a custom logo and although the discs are simple enough I'm a bit clueless when it comes to actually getting a custom brand 'end' - A look on eBay shows the end only for ~ £30 and then I'd need an iron, electric seems to just be a soldering iron (?!) or a more traditional 'bit of metal with a wooden handle' but that means I can't swap them if I ever get different designs I want to use.

So...my question is, does anyone have experience at all with this sort of stuff who can point me in a good direction?

Cheers!

Might I direct you to Laura Kampf...
She has more in-depth videos on each technique, as well, but ammonium chloride is my favourite.

How weird, I was recently watching her stone house repair videos, I'll take a look thanks.

Edit: 2 mins in and the idea of using a plain rubber stamp with ammonium chloride seems so simple and effective!
