Hello,
I've look through your mocks carefully and get general ideas about what you expected. Although I may need more detail to propose with more accurate price, scope, and schedule but I think you're going to build a site with following functionality
- bands and users management
- task activity monitoring
- finances monitoring, include sales
- messages exchanges and notifications
I've seen that you demand some visualize charts, it's fine since there's a lot of helpers libraries out there, just need to specify the data sources.
Which mean, I may need more detail about user stories, flow of activities, required data ... and so on. It would be great if we can discuss more about that.
Please drop me a message if you've got some text draft about specific requirements or more UI mocks that need to pay attention, also let me know if I missed any important things from your original requirements.
Thank you,
