Heavy MySQL/PHP & SMS site - ONLY BID IF EXPERIENCED

ONLY Experienced providers with Excellent feedback need APPLY. I will not respond to 0 rated users. The site I require is a business-to-business portal written in MySQL and PHP. It will be heavily search driven and users will post their services and request services. When such services come online the user will be SMS'd. This will be a subscriber service and there is budget for the right team. Design will be key, so send me your examples of PHP/MySQL sites and SMS
