Seeking agency to help with documentation and prototyping for MVP

Description

We are a startup approaching the end of our initial development phase. We purchased an template to help kickstart the MVP and started moving very quickly. Because of this, we unfortunately never wrote much of the documentation. Furthermore, we have some UI changes we made on an Adobe XD wireframe but have not had the time to finish it so we also need someone who can help us complete the wireframe and to prototype it as well. What we need: - User stories - User journeys - User flows - Personas - Any other initial documentation that is typically written for an MVP - Developer documentation (FRS, SRS, WBS, Product Feature lists, Use Cases, etc.) - Wireframe prototyping We would like to hire someone willing to complete this job on a fixed cost model (not hourly). Please do not send proposal unless you are willing to complete this job on a fixed cost model. We will provide access to apps and existing documentation upon receiving back a signed NDA. This is only one of several projects that we need this type of service so if we like your work, it can lead to other opportunities.
