Alright, in interest of making the GM's job easier, here's what we have so far;
Getting the harvest in and getting money+paying taxes, then getting the mine going, then getting the potter's guild upgraded to a full clayworks for mass brick production. Next, get a furnace set up for all the ore that should come in from the mine, finishing up the shipyard and getting started on a basic sailing vessel capable of navigating the river(something like a felluca), and seeing what we can do to spruce up our current home until the brickmakers and brickmasons get good enough to build a manor out of brick(might need to wait a few months for this). Also, once the clayworks is up and running, have the brickmakers and brickmasons practice their trade by paving the market area in sturdy clay bruck, and start paving the streets around the market after that's finished. Also, as a side project during harvest, see if we can get started on winemaking by fashioning a few casks and experimenting with a couple fermenting processes(and having our resident brewer assist), while also planting some of the grape seeds to get more grapevines. Did I miss anything?
Edit: You mean the brickworks? Not really, as we can make EVERYTHING out of brick, and the potters already have the ability of making small amounts of brick(they made their ovens out of vrick after all). If there is a cost, I'm betting it'll be small enough to allow us to get both the mine AND the brickworks going
