Hi,
I'm new to freelancer. I'm currently working on a couples website developed using rails( I'll send you the link if you are interested) I made that complete website where you can explore personalized date ideas and locations all over the world. You can schedule your dates, you can tag your facebook friends on dates. It was connected with Google places API, Facebook places API, Yelp API, Opentable API and so on.
Your idea sounds interesting, and this is quite simple one for me. I already made an iPhone app using twilio API, and also I know how to import and export XML and CSV files in ruby. I'm expert in responsive web designing, I worked on various front end frameworks like bootstrap, zurb, jQuery mobile. I also worked on 100's and 100's of javascript plugins. I'm expert in AJAX.
Give me a chance, I'll definitely make you feel happy :)
