I founded a UG with 2 friends. 7.500 capital, 2.500 each. From that money, we paid the notary. We drafted with chatgpt on our own and presented it to an attorney for review, ~300€. Notary ~1.200€. All in all, we are 1.5 years in, we still have ~3.000 left from that 7.500 capital. Obviously you're doing something wrong
