C# WMI query application needs additional queries adding

I have a fully working C# application that requests WMI data from the local computer on a schedule, it also uploads that data to a remote server. The remote server runs an IIS server to receive the data and inserts the data into a MySQL 5 database. The WMI queries in the C# application run using a script contained within the application. At a minimum adding additional queries will require modification of the app, the script, the IIS upload routine, and extending the database to allow for the new data. I have a number of other WMI queries that I would like to record the output from and would like you to take on this fairly simple task. In addition, I would to record some other data from the computer; a few text files, some registry keys, event logs, that sort of thing. Full details will be supplied. Please provide an indicative quote for the work and we can discuss it in detail. It is preferred that you have Skype and are available for a few hours while I'm normally available (6pm-12pm UK time). This may lead to ongoing work and the maximum bid is negotiable. Changes to the application must not add significant CPU load to the monitored computer. If this will take more than a day I need to have regular uploads of code to the vworker site.
