Recommendations required for Digitally Signing VBA macros

[Nyanko]

My company have asked me to look into purchasing a digital certificate for our macros, there are so many companies and options out there I'm getting quite lost !

Does anyone have any thoughts about companies to trust/avoid ?
Anything I should be aware of before diving into digital signing ?

Opinions, advise and suggestions gratefully received !

Frankly, I thought you create your own Trusted Certificate which you manage of your servers for your staff connected to your network. If there is corporate need then you could supply your certificate to third parties for them to install on their networks. Unless you are supplying a global market on VeriSign or similar
