We then put very cheap SEO and maintenance folks to ensure your rankings remain at the top, and your site runs blazing fast. Each of these people bill at different rates, so you get maximum bang for your buck. When you hire anyone at Quinji, you hire the team resources. You will not suffer if someone is not available.
