Another fact is that its content must be in spanish language. We will bring the designer team our repository in .rar or .zip, so they can work any changes on it. There are two main goals that has to be achived: * A time based calendar with a feature like a "booking system" for our services. We sell services online and we look forward to a system that sells and makes unavailable each hour of service when it is taken by a customer. * Methods of paying online, including Paypal and VisaNet. It is not intended to make the payment inside our webpage, but to rerout customers to thouse payment webs and then after confirmation of funds making the service sold "taken" and not available for future sells. The choosen team will have all the support from our CEO, who will be helping the team anytime necesary with information about our company so we can create a valuable product.
