The game could start like this:
the player starts working as a blacksmith in a someone else's shop and he earns a salary every day.
With this money he buys a blacksmith for him, but he has nothing, as time goes by he earns more money to buy the anvil to furnish the horse etc.
and after several days in his own blacksmith he can hire workers.
I know this sounds like a very ambitious plan but I'm sure your game is very promising and that you will get more and more away with it.
Never give up on this game, please, I really love to keep up with it even if it's been 3 months without updates.
I hope one day your game is on steam and I wish you luck.
