Being the Cheapest… Low balling can seem appropriate for several reasons. You’re a novice, so an entry-level price feels right. You want your price to reflect your own confidence, which is yet to grow. But just remember that you get what you pay for. Meaning if you offer cheap prices then you will most likely be offering cheap work.
What does everyone else charge? There are lots of ways to find that out. Find a freelancer websites like Odesk and Elance give some indication. Bear in mind that the rates are likely to be on the low side, due to the price-competitive nature of those platforms. You could even anonymously “mystery shop” another freelancer to discover their rates.
If you want me, that’s what it costs… You simply go ahead and charge what you want, with no second-guessing or self-sabotage, or even that much consideration of whether you will get the job. It’s simply the rate at which you will be 100% happy to do the job.
In order to find success at freelancing, you need to be sure that your work highlights your true skill especially when it comes to freelance writing. It’s important that you don’t do anything that flies over your head. Be sure to accept work that you will be able to complete for the price that you have agreed upon.
