Just use AWS?

At the moment, spot price on a m5.24xlarge is $1/hr for 96 cores and ~300GB of RAM.

That’ll get it done for around $100 — assuming you can checkpoint and tolerate the risk of a shutdown. (The on-demand price is $4.60/h; $475 total.)

Using the example in this article as a demo, on AWS, it takes $75 and 4 hours to crack a RSA-512 key, and it was the 2015 number. So it's certainly the correct choice here.
