Dave Young has written a post about the value of copywriting and how creating quality content and persuading users to take a desired action. Quality is immediately apparent, regardless of your industry, and it is not possible to fool people with a low quality service.
The point with the weather report is that you should always negotiate the price of hard goods, but take great caution in negotiating the price of services. Your very existence could depend on the results.
Let’s say you saved over $2,000 on your copy, but your copywriter couldn’t connect with even 20% of your visitors. Have you really saved money?
I had a potential client who chose to setup a Google Adwords account themselves instead of paying me to do it. They thought they would save money by researching keywords, writing ads and setting bids themselves.
Google Adwords is deceptively simple, but the system relies on having strengths in all 3 areas, something a new user does not have. It takes at least 3 months of trial and error to begin to make profitable campaign.
The person who initially declined my services came back to me after 6 months begging for help complaining they spent over $2000 and only made about %10 of it back from sales.
