I would like to develop a last minute hotel booking website and application. The product should be linked to hotel management systems (e.g. opera, pegasus, etc...) in order to maintain real time information about unsold inventory. The site/application will only feature selected hotels with which we have a direct contract with and therefore will not be powered by any 3rd party booking engine.
I also need someone to help with the design/marketing/hosting/payment gateways/security.
Please provide a detailed proposal explaining the architecture and the system process.
