When it comes to budgeting inside of your business, it is important you talk to someone who knows what they are doing. I would recommend hiring someone who is skilled in budgeting such as an outsource CFO... or a shameless plug for myself! Regardless, having a great financial team is important, because if you run out of money, then you will have other issues.
If you can afford a CFO, at least talk to them to get your budget in place and it will give you time to work on the business. Having a very skilled Bookkeeper is important to track your financial records and get a great CPA. Make sure they are great communicators, because many will not wave red flags if your business is in financial danger.
