If you want a quick solution but not necessarily the cheapest option you can try a set of sprint car chassis stands. https://www.racecareng.com/item/1580358-chassis-dollies?category=115994 They're good for up to #2000, and I've been happy with the mobility of being able to move my chassis around the garage and even swapping end for end in literally seconds. I did end up using a couple heavy cable ties to secure it to the stand for extra security and haven't encountered any stability issues. The legs are a little close together but I'm able to fit my creeper in between so it's worked well for me so far.
My car is further along than in this photo, I really need to start a build thread....
