City Guide with maps integration

It's a website to be constructed in HTML (possible wordpress integration, but for sure I need CMS integration of some type) that is a city guide, you can take this link as a base but it's somewhat different ([login to view URL]). We'll have listings of restaurants, bars, museums, and all of that but we need to have alongside the listing of "123 Diner" a Google Map marking the spot of it, on all listings. It also needs to have a Profile section where you'll be able to build your own "route" which is a map containing all the spots that you've marked as favorite, all in one map, your own map. I can provide much more information on this, I'm attaching the Sitemap of all the site, but first let me know if can tackle this one too and if you have the right people to do it. All the information will be provided or later entered, that's why I need it to have some sort of CMS integration, so the admin of the site can add, delete and manage all the listings. We also need to develop 5 flash mini games such as Sudoku, Tetris, Frogger, etc., just to entretain. The sitemap is in spanish, but it gives a broad look of the project.
