I'm not sure startup is the correct word the use. Anyway this website is not supposed to act as photographer/videographer portfolio website, but more for clients to easy choose who they want to hire.
When I said it's a free service, it's a free service.
Being able to show your work on the website will ALWAYS be free, you can print screen this post if you don't believe
You can take a look at carousel and you know what I mean, If you are only thinking about how to earn money from it before even starting, the website is not going to last for long.
