Then you do the pitch, and you have a business plan ready to go in the background. Your business plan includes numbers to support the idea that your business is a good investment.
That's the standard, but I should warn you that you're facing a tough uphill climb. Investors will have trouble seeing how they are going to double or triple their money investing in your business because it's mostly service, with no obvious leverage. How and when are you going to sell it? That's the only way they get a return on their investment. How will you be able to sell it for five to 10 times what it was worth when they invested, so they get a return? That's tough with service businesses.
