Saving to start a business

My wife and I are saving up to start our own business. We are putting aside about $2250 a month. We plan to open in about 24-36 months and depending on how much we save, it means less we have to borrow. We want to have around $60k to start up the business. We aren’t worried about getting to the $60k as we are already on pace to exceed it. I’m just wondering what kind of account I should put it in. I’m hesitant to invest too heavily due to potential losses but also don’t want to miss out on any potential gains. I’ve got a meeting with a financial planner next week but figured I would ask and get some additional opinions so I am somewhat aware of options and ideas before walking in blind.
