There is a software named Chef that can be used to install various Operating Systems/ Hypervisors like VMWare etc and finally install app servers / database servers etc.
This work (of installing different things) is done using a program called a Chef "Recipe". A Chef Recipe is written in Ruby
Now, I have a list of softwares/OSs for which I want Chef Recipes.
First, you have to find existing Chef Recipes and match them with my requirements and store them in my project management site.
After that, for any required software/OSs that you cannot find Chef Recipes for, you have to write them yourself. One advantage- you can mix and match code from various Chef recipes you have already found (just like you can use code snippets from existing programs in new programs).
Hence I am expecting bids lower than $45 as most of the work is simply collecting existing scripts and testing them to see if they work. I will provide you with a server with Chef set up on it- you can then run that Chef with your script to see if your script installs the desired software.
