Unless someone tells me otherwise, I'm going to assume that DF-like game mechanics are present.( (i.e. things like item quality, dwarfy jobs, etc.)
Na'Ine wasn't particularly skilled with his *Silver Axe* but it had been passed down to him through the years, and he made sure to practice in his spare time.
Obviously such was lacking in recent years, but he made sure to pitch in with the initial wood harvesting, and even did a bit of carpentry for himself, managing to make a wooden table, wooden chair, and +wooden bed+, which he setup in a corner he had claimed for himself, where he had temporarily kept with various goods.
After helping the initial workforce get all the goods to the site of the Mountainhome, Na'Ine quickly set about forming profitable trading partners, both within the Mountainhome (particular attention was given to forming relations with skilled weaponsmiths and armorers) and with nearby settlements (by either flying to them, or being sure to be part of the welcoming party for their visits to the Mountainhomes.)
With all these newly forged relations, Na'Ine realized that he needed to start actually trading, since his initial funds were being worn away faster than he had realized. (Probably spent something on the order of 50 gold on gifts/meals/booze, etc forming the relations.)
Na'Ine decided to set up shop in a small niche of mined out Earth Gems close to the entrance (5 tile's worth he figured) within the Mountainhome.
Enlisting the aid of an Apprentice Mason and Engraver to help in their training, he had the shop expanded and smoothed (to 3wx5d) and had two small rooms (2x2 each) cut into the earth behind the Shop. (one back room is an office/bedroom, the other is kitchen/pantry)
Thinking it would be a very nice touch, and maybe even something of an Advertisement, he secured the services of the most skilled Engraver, and had him engrave the Earth Gem tiles, offering him 5 gold for each Exceptional Engraving, and 15 for any Masterful Engravings.
After securing a few pieces of work from the Mason, (to include a couple of +obsidian cabinets+ for display cases, a *(white rock present in mountain) door* for the shop entrance, and two -(grey rock present) doors- for the back rooms, and having them all installed, along with re-locating his temporary quarters, and goods,) he set about setting up shop, being sure to arrange the silver weapons most prominently.
Satisfied with the Shop, and the modest accommodations he had created for himself, he had a small celebration thrown for the Grand Opening of the first, (and with any luck, most profitable,) shop in the Mountainhome, "Na'Ine's Finest"!
I really don't know how this is gonna work... but I figure this is split between the background turn(s) and the 1st turn. If you think it's too much feel free to split it into as many as needed.
Things like eating/drinking (water preferred) are automatic, unless I go out of my way to mention a change, (like hunting and cooking a boar or something)
