Pfsense + builtin health stats pack + extrenal device stats polling via serial

[KOTRz]

We are looking to work with experienced pfsense package developers to start developing a package that can do the following:
1. pfsense health stats polling on periodic time (5 seconds upto 1 hour)
2. additional stats polling over serial port and saving the stats within the RRDtool.
3. Saving all details under the package page so that stats can be seen.
4. possibility to use various polling methods such as serial, eth, … etc.
5. most likely the package will be of client/server style. but feel free to suggest.
As we are still in negotiation phase, we would like to see here experienced developers so that we can discuss budget with them.
