Coding and building a simulation/game app with already completed UX/UI

We have a table-top team/leadership simulation game of climbing Mt Everest. This is designed for extracting adult learning outcomes, and led in a workshop style by a single (usually) qualified facilitator. The half day simulation involves groups/teams operating according to resource constraints, facilitator-driven scenarios that challenge them from a decision-making or negotiation basis perspective as they make their way to the summit of Mt Everest. Uncertainty of success is provided by regular draws of 'chance' cards and gains and losses of resources are a given. A special set of conditions apply as team announce (having accumulated sufficient resources on their journey) a summit bid. The facilitator; upon ending the expeditionary phase of the session then moves to the debrief based on his/her observations of the partcipants' collective behaviours, teachable moments during the simulations and so on. You may have a look at more information on [login to view URL] ., and [login to view URL] The simulation is played on a proprietary game map, and includes many playing cards representing assets; as well as separate decks of cards representing elements of chance ( both good and bad) on the mountain climb. Movements are determined by special die rolls et al. Graphics in AI and PDF are available for developers. My intention is to consider turning this team and leadership simulation into a computerised, or web based version in order to eliminate the need for the current physical components of the game, as well as explore the possibility of delivering this to much larger groups in a single session from their laptops and/or handheld devices. We already have 23 screens for the digital app completed by another freelancer ( see a selection attached) These reflect screens showing asset lists, progress of teams, inter and intra team communication panels, as well as communication panels between the workshop leader overseeing the simulation as participants. communications will be via messaging within the app, as well as audio messaging. Messaging can be micro messaging to/from individuals as well as broadcast messages from the overseeing facilitator. We have avatar screens to allow participants to log in and select their role/avatar. We want to see a detailed workflow proposal with key milestones as to what aspects of the game can be achieved and when over a 30-day project completion date. If paying for chargeable 3rd party embedded apps and hosting services, why they are recommended versus other apps - and what these will cost. Subsequent to the coding, the project owner will have a hiatus of one month i which they will arrange for 3rd parties to beta-test the game play before returning to the project designer/freelancer for any tweaks needed to create the finalised, polished app ( for iOS and Android and tablets). Freelancers will need to make NDA agreements and IP belongs exclusively to project owner. Shortlisted candidates will likely have one or more conference calls prior to a final selection made in which they may have to provide a link to online games of a similar nature they have developed or discuss appropriate ways for us to reach a desired outcome. Milestone payments of 30% to begin, 40% when the work is ready to go to play test mode is proposed but final payment (30%) will be held until successful completion of project. Before you respond, please go to those two links I posted and familiarise yourself with the look and feel of the game/simulation. If you arent asking questions that tell me you have actualy spent some time exploring the product, or offering a Zoom call set of convenient dates you are unlikely to be considered. Responses to this project that come with a standard generic " I can do your project perfectly" will not be considered. We do not entertain unsolicited phone calls and messages unless messages are questions that indicate you have read the brief carefully - thanks
