custom windows service

I manage a couple of servers currently 2- windows 2003 and 1 windows 2008 and often have need to add a web page that we want to execute on a regular basis (every so many minutes or once a day or whatever) . I would like to have a windows service that I can just rename and install on the server and once it is running will run my app based on a config file - or something like that. I am not a server pro - so am looking for experienced professional that can recommend the best solution. I will need very detailed instructions on implementing solution to server also. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
