Budget: 4200 EUR Deadline: 35 days
For the full scope I would estimate 28-35 working days and a fixed budget from 4200 EUR. 500 EUR is realistic only for a prototype or technical specification stage, not for a premium WPF application with live API, WebSocket, SQLite storage, analytics, charts, export, logging and settings =/
COverage I would suggest - WPF on .NET 8, MVVM, SQLite, REST and WebSocket client layer, structured logging, background synchronization, connection state monitoring, chart module and export to CSV or Excel. I would also keep the analysis strictly historical and statistical, without any claims about future game outcomes.
A couple of questions before a final estimate
> Do you already have the legitimate API provider documentation and sample responses
> Should the first version include only local SQLite storage, or do you expect multi-device sync later

If we start pragmatically, I would split it into a short specification and UI prototype first, then build the production version. Measure twice, cut once - boring proverb, but software budgets usually respect it.
