Add new features to existing Ruby / Sinatra project.

The project is for some Ruby programming. NOT rails. No UI component. I have written a directory that uses Ruby Sinatra and need to have a HTTP POST or PUT operation implemented in Sinatra that will take a JSON file and store it into a Ruby hash. More work to come if this works out well for both of us. The Sinatra Web service needs to respond to put or post requests. Upon receipt of the message your new code would validate the inbound data structure and then parse it into a specific ruby hash. I have a number of similar projects, on the same source code base, after this one such as to enhance my http get code to return different json or xml documents. I wrote the proof of concept and don't have the time to keep coding the rest of the project. I have a flexible timeline. If this sounds good let's get an agreement in place establishing that this is work for hire and then we can get started. If you are interested please let me know. I'd be glad to provide more information.
