Why hire a proofreader?

Why is proofreading by humans so important? Spell checkers don't catch things like "their" and "there," or the names "Taylor" and "tailor." It looks unprofessional when your blog or webpage has errors like this. They also don't check for consistency between, for example, 3 and three. It takes a human to see these errors. I have low-cost proofreading services available to take this burden off of you. Proofreading is time-consuming, and I can help with that. You write it and I will proof it.
