Do I Need To Create Professional Looking Videos or Can They Be Unprofessional But Packed With Value

I have some confusion about creating my first course, i see professional looking video courses here on udemy and wondering if i can create a not so professional looking training video course but that is jam packed with VALUE over looking professionaly made

Can I contact udemy support to ask them about my concerns and will they answer me or there is not option but only this community to get answers

i wish to create non professional youtube style unprofessional looking videos but wonder if they will be approved by udemy and have others on udemy created non professional looking videos that are best sellers despite the professionalism

At a minimum, what will get me not approved if i create youtube style training videos that are personal and raw with me talking on video or screen based recordings or how to use autoresponder tools

What is best way to approach this should i create a sample video submit and ask them what else it needs to get approved to see how raw will they accept my video

Where should i host my training videos while creating them can i host them on youtube as unlisted or better to host them with amazon hosting for videos they may take too much space on computer and crash my computer
