smart kids games & shop corner on free web site

Ok I want a free game/school shops website setup for my grand daughter and her mates as be more of a learning aid and toy to keep them out of trouble Its to be a games site with the lot of the old games like asteroids pacman etc as i intend to poke nose in and play against them on the old favourites bringing back memories of my youth lol and showing that parents can still beat them., Lot of fast games that dont take lot of time, and a reverse auction type shop so that parents etc can put some nice donations up etc The idea is first page will be introduction to say what site is about And be able to switch on few games just to show kind of thing inside and maybe give challengers from other classes a practice go password to all pages so some can be opened and closed keeping some pvt like swap and trade deals and others for select few Its for a members only site mainly etc so you have a standard web site members list The second page be games that have a top scorer list where players can put their name on the score board Where games can be transferred from bank of games on page 3 or page 2 and 3 have the same games that can be turned on and off so it seems they being transferred from 2 to 3 so you get the effect where page two is empty of games page 3 has loads but are closed and locked with password she can transfer say a tennis game to page 2 and set a timer up where her friends has a set time to beat her score on the score board before say Friday lunch time, when timer gives out and the person on top spot of games board is the champ then she can transfer that game back to page 3 or may be easier just to turn it off and then turn another games with score board on games may be set up with other classes so some members will be there as guests and wont be able to see certain pages or that may only be members for the run of that game, as I like other pages to be able to use as a shop or a reverse auction type of thing all these things are on the net free so it just means putting together which is fiddly but a decent programmer can knock together pretty quick and cheaply as we not looking at anything special or involved here the free site needs to be easier to modify by youngsters so nothing complicated so looking at quick job although not urgent
