Anyone in Melbourne willing to lend me an RTX 4090/4080 for one day?

I know this is a long shot, but is there anyone in Melbourne, Australia willing to lend me an RTX 4080 or RTX 4090 for a day so I can test my software with it?

I don't know how you'd address the question of trust - i.e. me not running off with your card, but I'm open to any ideas for solving to that.

No doubt you know an RTX 4090/4080 costs > $2,500 and I just don't have the money to be buying cards to test on, so hoping to find someone kind enough to help out.
