Do not fall into the trap that your translation project needs to be budget-driven. Deadline, formatting, style, all of these need to be factored into when you ask for a quote. That is why there is no such thing as a "standard rate", simply because there is no such thing as a "standard project". Please state all of your project requirements upfront and I will be sure to consider all aspects of it and provide you with an accurate quote before I get to work.
