No one is just "going to find you" out of the blue or look you up like the big boys. You have to pound the pavement. But if you put in the work, not only will the hobby reward you with friends and enriching experiences, but you'll be able to afford it with trades and froglets. It is very attainable to have this hobby "pay for itself".
Don't forget about word of mouth, this can hurt you or help you so honor your dealings, advertise and be as upfront and factual on what your have and bred YOURSELF. People listen out for who to trust and more on who to avoid. Keep what you like not what you think will sell. And don't be an asshole and tell someone you never actually guaranteed live arrival. Tads, frogs, bugs or whatever your quality, husbandry practices and dealings are your rep, You only get one and this hobby is small enough everything gets around.
And don't rush to build a collection. I know of many who dove into thumbs in the last year and realized they are not prepared only after causing issue, harm or death to the frogs. Research and take it slow.
