Thanks for the responses thus far; you’ve both been a real help.
Since most of my rendering will occur during business hours, there won’t be much benefit to the render farm strategy. I guess I’ll look into increasing the RAM (currently I have 2 GB), installing Nucleo Pro 2 and basically learn how to render smarter (low res outputs for preview, use proxies, etc.).
As our projects become more intense I’ll look into dedicated render farms, like the one Boxx Technologies has. I’m sure it will be unbelievably expensive, though.
