Hello. I'm Pablo from Argentine.
To develop your project, we can do this using the technology you mention and also use it in conjunction with html 5 canvas + js.
I am a senior developer with over 10 years experience.
I have worked with companies such as Disney World, motorola, coke-cole. Adidas, and more...
With the cost, is included 1 month of Community Manager (free), for impulse your site on social networks, like facebook, twitter, and more.
Thanks.
