Ruby on Rails C Extension with RubiInline (small job)

I am looking for a Ruby on Rails developer to build a Ruby class with a method that has multithreading functionality written in C (RubyInline). Here are the requirements for the multithreading method - must be written in C using RubyInline - is able to accept 2 VALUE parameters: (1) an array of elements which will be placed in a "thread pool" and (2) the number of threads - will spawn a number of threads and supply them on demand based on the number of threads requested - threads automatically close when there is no more supply Here are more specifics of the simple application that needs to be built: - an "User" model. The database table can have only one column: name (string) - a ruby "Job" class which contains the method with the multithreading functionality. - the method should be able to accept a large array of names (e.g. ["Adam", "Mary",……………,n]) and an "x" number of threads. Each name is added to "users" table through threads. Thank you for your consideration.
