Hello
The requirements you provided were very high level. Based on real life experience of lotteries, I can summarize what needs to be done in a little more detail:
Allow the user to register.
Authenticate the user and let him in.
On the homepage, display :
1) upcoming drawings ( probably for the upcoming week) , prizes.
2) link to view the past results
3) link to a help screen how to play
4) link to a screen to deposit money.(This screen will have lot of functionality)
By the way, I am not sure what is exactly on your mind. Online gambling is not allowed in many countries. However, I hope you are already aware of all that information before posting this project.
I am ready to work with you both to help finalize the requirements, do the design, develop, host and maintain the application. Of course, maintenance agreement will be separate from this bid amount.
Thanks & Regards,
Ramesh
