Speeding up this process might be pretty tricky. Because you might want to offer your potential customers exactly what they need. And understanding what your customers want requires some time. If you say you can handle all the work yourself, you might want to understand better what is the thing that you need to speed up.

I research, write, have someone proofread it, assign the website design to someone, then test, test and test, this is what you need. Testing will help you understand better how to do everything better and automatically faster next time.

I hope this helps,
