So, I'm going to assume that you are going to be hiring a financial advisor for the sake of your small business or freelancing. This means that you will have to hire a qualified (and certified) advisor who knows their stuff. There are several ways that this can happen, in terms of payment. 

Most people can hire a financial advisor through three different models. I'm going to go through each of them so that you can get a better idea of each...

FLAT RATE FEE
So, this is kind of a misnomer, because it's actually a charge that will be based on the value of assets that they will be managing. With a live, in-person financial advisor brokerage, that rate will be around 1 percent of what you want them to manage. 

For example, if you want them to manage $1 million, you will have to pay them $10,000. If you want them to manage $100,000 of cash flow, you have to pay them $1,000. If you have an ultra-high asset book, they may drop the rate to 0.5 percent or less.

ANNUAL RETAINER
Most people who hire a financial advisor with a retainer fee can do so for $2,000 to $7,500. Businesses might be around $5,000 to $8,000 on average. This gives you services "on call" if you need them. This will give you services like creating a financial plan, having adjustments, answering questions, and more.

PER HOUR
Let's say that you need to just hire an advisor for a day. You can do so for $200 to $400 per hour, depending on the firm and the tasks that you want them to help you with.

PER PLAN
If you just want a good financial plan for your business, then you can go buy one for $1,000 to $3,000. This will give you a customized plan that will hopefully steer your biz in the right direction. However, you won't get adjustments or followup like a retainer would.
