Have you tried looking through fellow REVA's websites to see what they charge? Perhaps fine-tuning your search to those who specialize in the same services you do? When I was first starting out as a virtual assistant, this was the quickest and most effective way to get my bearings.
@Tricia, we can't openly discuss rates, in depth, on the board due to various laws about industry price fixing (applies to any industry). It's also off-putting for potential clients who read the forums - and they surely do.
I'd also recommend reading through the
Rates and Billing section on VAF for more information to help you set your rates.
