A place where I write on turnkey business software
Most sellers will provide you not just technical support any time of the day and night, but also hints and techniques on how to go about online business marketing, advertising and promotions. When you buy a turnkey website, you are its sole owner and the seller can never be involved in your business except as your support. This is a great advantage since it also means you are in no way have hosting commitments with the seller. So whenever you want, you can then move your site to different host. And since you own your site, you can sell it anytime you want.
