Your business, as many people have assured you, is completely fine. It's actually a great service for some businesses.

Find bigger clients, this will allow you to keep your billings high if your worried about bottlenecks and hiring. Look into https://elasticsales.com/ for cold calling as a service.

Why not do both versions of the business? Create a separate brand and package together services, flat pricing and slap on a healthy markup to offset your advertising and marketing. PPC, Social Media, etc would be great for this.

Get that monthly revenue up and then build a team around your processes. Hiring will always be hit or miss - just make sure your hiring them for what they know and not what they can learn - if you want to save time.

Best of luck!
