Classified Ad website

Needing to build a new website ([login to view URL]) that needs to be SEARCH ENGINE friendly, MOBILE PHONE friendly and ADMINISTRATOR friendly and that can be adpated to a mobile app later on down the road. There is NO script or website pages or code to change, upgrade or modify. From scratch only. This website is a free service to users. It lists 1) people who NEED A RIDE and 2) people who will OFFER A RIDE or have a car. It is only used in the US and not other countries. It is only CITY and STATE use. No google mapping or other major work. I would like my opening (index) page to have my logo for RideShareUSA and a US map along with an alphabetical listing of states. Similar to this: [login to view URL] Thus, upon visit, the user can choose a State and then a City that he/she is starting from. Under that State will be all cities posted (cities listed are from posts only) with people needed rides and people offering rides to/from various destinations. Only in the United States. I would like to be able to incorporate banner ads (maybe rotating) for paid advertising (via PayPal only). I would like the theme to be simple, colorful and super user, as well as, admin. friendly. I am not in a major hurry. 10 days to a couple weeks is okay. I’m more concerned with price, quality and that can be converted or used with a mobile app in the near future (another project, more than likely, for the winner of this project. I need all documentation, full rights and I may use this on 2 different registered web domains of mine. So with no restrictions, please. I CANNOT and I repeat CANNOT go over $250 and would look to award project to someone in the $150 price range. Site Function: This is a site of ridesharing, car pooling or people looking for a ride or offering a ride. Maybe they will go across town, only one-time or 5 days a week or maybe from one state to another (ie. Los Angeles, CA needing a ride to Miami, FL. Perhaps, a college student needs a ride back home for a weekend, or a daily carpool ride to school, etc. The copy of the posted ad can have a detail description of needs and/or can include contact information directly. However, I need a contact form that can be used ALSO so that people can keep their personal info private. When posting an ad or contacting an ad poster, the user has to be logged in (cookies are okay). I do not use nor want to use skype or gmail. If frequent communication is necessary, you will have access to my cPanel and can set up a chat or forum that only you and I will use. Lastly, because I drive a lot, I don’t always have good access to the Internet. If I don’t respond to you in a day, please don’t be frustrated. Thank you for viewing this project. I look forward to working with the person, group or company that can understand what I have written here. Bob
