I use the Genesis Framework, which is why I can build premium WordPress sites for a low price. The Framework with Sample Child theme costs $60, and there are multiple choices of free child themes.
Or you can buy the Framework with a premium theme for around $130.
See pricing below:
Genesis Framework by StudioPress
The Genesis Framework already powers over 500,000 WordPress sites, with search engine optimized code, airtight security, instant updates, customizable widget and layout options.
Best option at $5.99 per month for up to 3 years. Their support is excellent with free backups included.
Cheap if you have just one small website at $3.95 per month for up to 3 years.
Support is not great.
