Build a hotel app for a management company

Medium sized hotel management firm looking to develop an app to serve leisure and corporate travellers. We would like our app to be very similar to the HHonors app for context but it would also need to include the following additions: - seperate corporate login for corporate clients with negotiated pricing - guest directory for each hotel Please be aware project will entail a lot fo data entry as we currently manage 13 hotels. App will need to be very modern and user friendly, so we are requesting someone with graphic knowledge and understands appyling layouts. We are a company who works closely with our projects and would require weekly phone calls to brekadown project and progress. We would like the ability to manage certain components of the app once complete such as room pricing, pictures or addition or subtraction of corporate clients for login. We are looking for a long term partnership with potential for extra revenue to the right app developer.
