Hello, I'm Tyler, CTO of Turing Lace, an open-source software cooperative. Our team consists of Julia Longtin and Lisa Maginnis, two expert programmers with code admitted to the Linux kernel. We are interested in working with you to complete this project, but we need to define your exact requirements to provide an exact bid. We estimate the total cost of this project to be between $15,000 USD and $25,000 USD, due to the fact that you require a mobile app deployed on three (3) separate platforms. We are a North American company, so we cost more than international software development companies, but make up for it according to our terms: 99 day feature/functionality guarantee, 50% paid up-front, 7-day project kickoff and specification determination, and several clauses for protection for yourself and my company. We believe that it would be at least worth discussing your project to see how feasible it is for you to leverage our expertise. Thank you for your valuable time. We would like to discuss this further.
