Skills - at this point I'm definitely struggling with design and UI/UX. The only man besides me has similar experience as mine. As I said, I'm fine with hiring freelancers but my experience with them has been similar: Clear requirements, deadline and name your price and I've never questioned it. 4 people have taken the challenge so far(a single html page, no animations, or anything flashy-clean and simple), I didn't get a single question or feedback from them, 1 month later I go to the freelancer mediator to get my money back. As much as $3500. It's absolutely hopeless.
I agree with the statement that tech people are generally lazy but in recent years it has become worse. I honestly would take anyone that would put a minimal amount of his/her time at this stage. I'm that desperate.
Have you ever dated someone who has that type of attitude? Someone will stick with you for a week and then leave because it is toxic. I don't know you but that is how your messages are coming off.
If all you need is a designer and UI this should be no problem. There are tons out there. Just go on https://dribbble.com/ and find someone you like and hire them.
I am not sure what you are trying to build, but build something that doesn't need UI/UX is an option too.
I ask that seriously and say it harshly to get your attention, have you taken a hard look at your vibe and yourself?
#2 - What skills are you specifically missing to build a product? Design? People? Customer development? If you could build the perfect co-founder what do they look like?
