I know. It's a global thing. People can write cheap if their costs of living are cheap. In comparison to ours, that is.
And yes. I know. Avoid the cheapskates. Don't even go there. And I don't, unless it's to marvel at the scintillating people skills some of these buyers have. "You must have expertise! We want expert copy! No grammer [sic] errers! [sic]. NO PLAGRISM! [sic] It must pass Copyscape or we will come round to ur house and rip ur ears off and eat them and then roast ur children alive and eat them too!"
You just know that these vermin are going to bitch about your copy, question every invoice, refuse to pay you for your work (while keeping your articles for uploading elsewhere) and turn your life into a pit of snakes.
Every time I see one these loathsome things on somewhere like PPH or Elance I'm amazed by the number of people in the UK, the States, and Europe bidding for the damn jobs. They're paying the buyers, really they are. Factor in the costs of writing - even if you're doing it to make a few squiddlies here and there - electricity, heating, wear and tear on your computer ... Even if you live somewhere cheaper, you're intending to work for people who think you're one genetic leap down from a bucket of giblets.
I blame Al Gore, since he claimed once to have invented the internet. The modes of supply, demand and delivery have forever changed the way writers find markets and buyers find commercial copy. Now we're all in the same wrestling ring and the only winning strategies are to either stick to print magazines and journals who haven't yet reduced their own rates to bowls of gruel every Friday, or find online buyers who appreciate a fine turn of phrase and rain cash down upon you in return for your glittering creative skills. Anything else is just a dentist's appointment waiting to happen.
