A directory/Catalog app for booking and hiring musicians.

I am an Irish musician with a detailed knowledge in the process of securing and performing at events. The app would serve as a platform for musicians to have pages about their groups, which allow app users to see photos, references to the musicians websites/Facebook page/YouTube channel. Their would ideally be a rating and reviewing option which users can access on each musicians page. A search feature would be great in allowing users to find specific bands or groups. The directory would be categorised predominantly be genre of music played, but also by type of group/soloist performer (examples in images attached). The ability for a user to send an inquiry to the musician they want to perform at their event is key. It should include their budget, service description/requirements and the clients contact details. If the musician accepts the inquiry, the user would then be invited to send a deposit (amount tbd). Any advice on the way to do the financial transaction would be appreciated, such as a version of Paypal, Stripe or some other safe platform. I am open to suggestions on any improvements or features that would ease the developing process as I am working with a limited budget. Attached is images of the app I made on an app developing website, which didn't include all the features I required, but it gives I think a nice foundation to work off! I look forward to hearing back from you, and please send on a rough quote regarding the estimated cost of developing the app. I really believe in this app and the budget will be dependent on the quotes I receive as I want it done right. Thanks very much.
