Hello, we offer an iterative approach to protect the investments and guarantee our results. Also we expose all the development process to our customers. You would see the dirty but operational software version for $800 in two weeks. We really love to design the convenient applications: UX planning and responsive UI is what we always offer in priority. Minimum Viable Product may cost about $4000 and be released in 1-2 months. Sincerely, Pavel and my ExtPoint team.
