Charity auction advice

Anyone work in the charity sector, or I guess in the legal field?

I’m planning to auction off some old pieces of public art that I’ve had recommissioned for a local homelessness charity.

I was going to run this as individual rather than going through work and it becoming a corporate thing. But what should I know? Is there anything that could go wrong here? What about handling the money? Can I even do it as an individual??

Do you have an idiot’s guide to running charity auctions (it’d be an online thing…I think? Should it be? Is there a good bit of software for this?)

Help.

Thank you!
