Here are two ideas.

(a) Would need the home page with the boxes, a rules page and a prizes page, same as the photo contest, they can use them or not.

(b) Probably a stand alone platform.  I want it to be like your other scripts with an installation wizard and to be embeddable with javascript tag like the slider.

Both are doable but you have to choose one. (b) is much smaller than (a), so maybe it's a good idea to start with (b). And we can add (a) in the future after checking the marketability of the idea.

>A player/member would come the the site and decide how many prize boxes they want to buy and pay for that many. Once they have paid, they could click on that number of boxes and the prizes they won would take the place of the pics (probably as text).

I'll stick to "a player" instead of "a member" because member implies a regsitration to play.
I assume, in your plan, anyone can buy without prior registration.

>The member would get an email telling them what their prize(s) are and the admins contact email.

So the player doesn't know what prizes are until he pays and receives the email notification. Am I correct?

Would you give me an example for a prize box?
What kind of text/pic in the box will we see?
And what prize will be given for the box?

I am having difficulty visualizing it.

Maybe something like this? The box says "Once upon a time in midwinter, when the snowflakes were falling like feathers from heaven" but it never says what you get when you pay for it.

After you pay for it, you recieve an email that says "Congratulation! You won a book of Snow White!"
Am I close to your idea?

I didn't reply to other comments of yours (especially regarding the admin area).
I'll do it after I understand how players interact with prize boxes.






There would be pics on the front page same as now, these would be uploaded only by the contest owner, they could be whatever they want to use.  Would need the home page with the boxes, a rules page and a prizes page, same as the photo contest, they can use them or not.

A player/member would come the the site and decide how many prize boxes they want to buy and pay for that many. Once they have paid, they could click on that number of boxes and the prizes they won would take the place of the pics (probably as text).

The member would get an email telling them what their prize(s) are and the admins contact email.

Admin Area:
I would like the option of reusing or not reusing the pics/boxes so if they had 10 of a certain prize and maybe 5 of another it would be able to be bought that many times.  If they only had one of each prize they would have that option to set in the admin area.  So in their admin they could set each prize for whatever number they want, once that number has been bought, the box would no longer be available (grayed out or just gone, either is fine).

In the admin area:
They could see who won what.
How much money they have raised and the names & emails of winners.
They could set the contest start & end time.
Set what each box costs, with the option of setting variables like 1 box $10, 2 boxes $18, 3 boxes $25 ect..., so a choice on the prices and number of boxes for those prices, like what the photo contest has OR be able to set a specified price for each box individually if they want to do that instead.
Upload the pics and write the prize description for each
Chose whether to have each prize only once or more than once.
 
Probably a stand alone platform.  I want it to be like your other scripts with an installation wizard and to be embeddable with javascript tag like the slider.  The difference is it would have to allow for more than one admin.  I want the Super admin option (for me), I can see everything, and the regular admins who only can see their contests.
Does this sound doable?
