Hi, first off, you need to have a great appealing website... WHICH YOU DO!!! Your site looks great!!
Then you need to know your niche.
- What is your competition doing?
- What are they doing?
- Where are they listed?
- What plans do they have?
- What can you offer MORE?
- Why should they come to you and not stay with Godaddy for example?
- What is your support response like?
- Do you help with transfers?
- Payment terms
- Refund policy
- What do you do if clients are not satisfied?
etc etc...
These are the questions you should be VERY comfortable answering.
Don't worry, it doesn't and never happens OVERNIGHT - lots of work and dedication is involved.
Good luck
