Yes, but that is a minority. We all had to eat a lot of beans and Top Ramen to break in. And wherever you have a newcomer to the industry, the clients are lined up to exploit them.
In say, the construction industry, there are things in place to prevent this. It's done to benefit both the purchaser, for safety and some form of quality assurance, and the industry. On the 'net . . . chaos.
I've been visiting and working from these sites for quite some time. I read a lot of posts, look at a lot of profiles, wade through tons of RFP's, and on sites with open proposals, see what many of them are "proposing."
I'm not a writer by trade, but for writers, it's even worse. some of these people have grown to expect 250 word articles for as little as $1 each. This is no exaggeration.
Where providers get it wrong is simplifying the "what people want" down to the lowest price. You bid $50, I'll bid $40. Then $30. Then $5. Clients don't understand, and hey, if I can get it for $5, why would I spend $50?
When you understand it's "not about price" and justify your proposal with experience, it changes the playing field. A good proposal, one you can stand behind, can easily close with 3X the proposed budget. I know . . . I've done it. My opinion is when you open a business deal, it's very seldom about price. If it is, I don't need that work.
Sorry to derail the topic . . . just sayin'. :-)
