Write some Software

I am looking for a Shell programmer to write a clean and commented script (entirely in Shell using only tools that are available by default on a CentOS 5/6 server). The script should collect the following statistics and POST the data to a given URL in JSON format: 1. The system's used memory in MB 2. The system's cached memory in MB 3. The system's free memory in MB 4. The server's load over the last 5 minutes 5. For each mounted disk on the system: 5. i. The kbytes written since the last run 5. ii. The kbytes read since the last run 5. iii. The total inodes 5. iv. The free inodes 5. v. The total capacity in GB 5. vi. The free capacity in GB You should also produce a second file that will download and install in on the system (i.e. create a cron job to run it every 5 minutes). Both scripts should be compatible with CentOS 5 and 6, and ideally Debian and Ubuntu as well.
