Start looking for a groomer and boarder now. Also, a doggie daycare that could provide socialization a day or two a week once or twice a month may be worth it. A clicker, leash/collar/tag, KONG toys/filler, crate/cover/mat, bowls, puppy pads (I didn't want these but interceptor made them necessary even though I've never needed them before), training treats, regular treats, food/food storage, stuffies/toys, chewies/toys. 3 rounds of shots (pup should come with the first), a comprehensive exam, deworming, microchipping, spay/neuter, flea/tick, heartworm, lyme, rabies, and unexpected expenses for things like UTIs/ears/eyes depending on breed. City license and registration. A formal trainer. Umbrella insurance (since you have children not your own on site; more CYA than anything). Pet insurance or a wellness plan or a sinking fund. We use wellness plans the first year at $72/mo, and it covers all exams, deworming, flea/tick/heartworm meds, and spay. Insurance would have covered cancer (had it been found sooner) when we put our 7yo down last March. Both could be replaced with a sinking fund if you prefer to pay yourself monthly instead.
