Congrats, it looks good and translated well into English. A platform for independents to upload their event and take bookings would be good. These types of events attract a local market/patronage and so that's where your market is for each User (Independent). So in terms of business models you could open your platform for free to the User (independent theatre/event/act) to add their event and take bookings and they could in turn charge local restaurants, businesses etc to advertise through them to their local market; your platform takes a commission of the advertising revenue. Some functional outcomes your app should offer Users; 1) advertise their event and take bookings (done); 2) demonstrate to local businesses the demographics of audience they are attracting to their event (you can capture this on booking-no big deal) 3) provide simple digital marketing tools for the User to promote the event and their advertisers (off the shelf integrations are fine) and 3) collect advertising revenue from participating customers. How all this comes together is a considerable undertaking but you already have a working MVP you just need to work with Users (independents) and Customers (advertises/businesses) to get the product right for both and a businesses model that supports growth. Do that first before building any scale into your product. Good luck and congrats again.
I recently committed to a CRM after trying Insightly, Capsule and some lesser known apps. I settled on RelateIQ. It's a Salesforce company. I have found it really good particularly for integrations but it's expensive. $1000+ for a single User or what they call a Seat. I also have a subscription to Triggerapp which is a CRM for small Creative firms. It does everything and is by the far the best UX and much more affordable than RelateIQ.
Everyday interactions present opportunities for further exploration. I get my projects from problems I encounter during my normal interactions with people. Then I try hack something together for fun. My most recent project is hacking a thermostat with a Raspberry Pi 2 and mobile app to notify small shop owners when their freezer temperature has risen above a certain temperature. This project came about from a interaction with my local grocer. I grabbed some Ben&Jerrys out of the fridge a few weeks ago and the shop attendant apologised. He couldn't sell the ice-cream because the freezer power was cut the night before when a cleaner accidentally tripped the power cord. The ice-cream had melted and was a write off. The shop owner had to leave the stock in the freezer until the insurance delegate arrived to confirm the write off. The shop owner gave me the idea of an app that would notify him if it ever happened again. He wanted to do it himself but didn't have the technical ability. I didn't either but that was an opportunity to learn on a real life problem. It doesn't matter that there are commercial alternatives available. It's something fun to program and I have a willing participant to trail it on. Keep your eye's and ears open. Real life problems are often more rewarding to solve than projects on hobby sites.
no-reply emails are typical of companies like Paypal. It is a terrible customer service experience. But the worst UX is when you have to complete a web form to make an enquiry but don't get a email receipt of your enquiry. So there is no proof you submitted an enquiry and unless you copied the text to another file you have no copy of exactly what you submitted. If you are lucky enough to hear a response it's from a non-reply email address. I experienced this exact scenario recently. I thought it was blatantly cynical.
