I'll dispell any rumors before I start...I'm a hardened Army Ranger that runs a STR service and I have very little knowledge about requirements for apps and developer prices so please ignore my cost estimate below and provide feedback as necessary.
I'm looking for requirements and quotes to build an app that provides Real Estate services for shared spaces. I'd imagine there are levels to this that include type of data, data size/requirement, # of users etc.?
I'm also open to the idea of shared investment, whereas a developer brings the tech solution and I bring the service.
