Ok, here's my computations. To keep it under 800 chips this breakdown works.
You need to figure if you want plaques for rebuys, I'm not sure how many rebuys you need (not sure if you have unlimited rebuys/if just one per person then maybe 12 rebuys worth is cool, you can use 12 $10k plaques or 24 - $5k chips, maybe add a few more) You probably won't color up the $1000 chips so the 24 color ups could be used as rebuys (maybe get another 10 or so then grab a few plaques for fun. You can play with the starting stacks, but if you add any chips you will skyrocket above 800 chips.
Maybe add 5 or so to each denom for spares or round up totals to even numbersto get to 800
