Omg this is me!! I was so nervous to do so too. Especially in such a saturated market. (Photography lol) so the way I did it was slowly. I created a private closed off Facebook instagram and website, honestly I did this for about a year. And slowly uploaded content. Meanwhile on my private Facebook account I was uploading pics I was taking, once I was getting contacted to the other people’s pics I did it a couple things same thing. And shortly after that I opened everything up to public so I have a fully operational page with a history of content and people know my name. I also bought the domains a year prior. So I had owned it for while I needed it. I was much too nervous to just go all out I eased my audience into it myself too. But there’s really no such thing as a saturated market if it’s a creative outlet because no one can copy your creativity they can only try. Even two photographers won’t produce the same picture under the same controls and circumstances, not gunna happen. If there’s one thing I’ve learned from watching people with success if the way they lean into it and believe in it, or your buyer/customer/client won’t if you don’t.
