Hello, how are you doing? I was looking around and got interested in your project. I understood that it is a simple project (even if you need to call an API outside the Drupal system) and with a medium difficult to implement. The StackExchange way I believe it is a better way, as you apparently don't need something more robust than a complete module like Web Service Client or even Services module (they are better when you have multiple interactions to do).
I need to confess I don't really know about the Amazon AWS API, you will have to specify detailed what you need and what to call, what will be the response and how to use it. This form is a node or a webform or something else? When you say it has to print the returned values at the screen, will they also be saved (as node, webform entry, etc.) or just printed? If you can provide the link for the current website, it should help to understand better too. It also can help to get a better time and price for you too.
Just to present a little about myself, my name is Marcelo and I'm from Brazil. I am a CS graduated with more than 17 years experience in IT market, and +8 years experience with Drupal, mainly development, SEO and performance tuning. I have other some good works at my portfolio. I'm closer to 100% conclusion rate and positive feedbacks here at Freelancer.com and I intend to keep that.
If interested, call me on chat or award this bid!
Regards,
Marcelo.
