setting up a rendering server with AE/adobe after effects

Hi - I need someone who knows how to set up a rendering server with an online server using Adobe After Effects to help me. I'm not sure exactly what is involved, so have set the budget as $30-$100, but am assuming it is a "relatively" easy thing to set up. If it is a lot more work, just let me know. Basically, what I want to do is this. a) I have an online webhost running linux. I want to know what 3rd party tools I need to install to do rendering on their machine, and whether I need to use a dedicated server for that (I am using mid-level server, but don't know if I need kernel access/etc for this). b) I'd like to be able to take an After Effects template, and be able to substitute some phrases. (I.e., so I can render an AE template on the fly, but swap words. So I might render it saying "Hello World", and then simply change the phrase to "How are you" and it would render that). c) I'd like to render it as 1920x1080, and if possible 4K (4096x2160). If that takes a lot of CPU cycles, etc - I might just stick with the 1920x1080 for now. But I'd also like to know what I need to what I need to do, whether it is a simple shell command something like [login to view URL] /resolution:1920x1080, or something else, etc. Ideally you would be english speaking, north american or european based, and actually have done this. If you've done this - please point me to a web address with a sample rendering engine you have set up. Thanks!
