Re #1:
Typically said posts are under Show HN. So the fact you put it there originally was right, I think the mod was wrong in that case. If it said Show HN I would have objected as much.
But I think the other part is because the only piece novel here is the price. There are a lot of services that do what you (and I) do. Unless there is something I missed.
Again, that second part is mostly moot because I don't think I would have cared if it was "Show HN"
Re #2:
Typically in that range I give the client an API, a single front-end (mobile or webapp) and all the database and design that goes with it.
I do really appreciate you trying to cut the crap and focus on shipping functionality. I also like how some things that people could call a negative you turn into a positive (like cutting edge tech and lack of fancy sales decks). I'm not calling it a negative mind you.
I do have one question, and feel free to not answer if it is prying too much. What do you pay the developers? How many of these a year does it take to pay their salary?
In the interest of transparency: our staff is all US based. Here it is $75k - $150k USD and if we have them on 3 to 5 projects a year we've paid for them.
Again don't answer if you don't want to. I can hide behind anonymity which lets me be a little bit more transparent.
Anyway, good luck to you!
