Toy-ing with a business opportunity !!!

Nobody in this not-so-empathetic world would ever want an innocent child wailing for something that he/she wants badly. Even more so if that pity thing is a toy and that too when in today's fast moving world when that toy is just a click away. Yes i am very much talking about the "www" power of the internet.
I was just thinking one day of one such website/web-hosted application which could enable me to order toys online. After searching for such sites , i could not find any well established toy selling vendor with a good presence online.
Me being me  , there i saw a business opportunity for an application which could serve the purpose for the parent community and could make good business for the toy making firms or merchandises.

I contacted an old friend of mine , Atisha,  whom i knew from my post graduation times and also was aware of her application building skills owing to her developer background in a famous IT MNC. I know she could do the task well.

As a responsible customer , i gave her the following requirements and also told her that the specifications were open to discussion on all ends and she could even find and suggest any loopholes.
===============================================================

The specifications include the following -:
