For translators who are using bidding websites such as proz.com, you may get your quotes declined because your proposed rate was 'higher'. I mean by 'higher' here 'higher' than other bidders' rates. Unfortunately, many people who speak English and Arabic claim they are professional translators and hence they give such ridiculously low rates to clients. It is sad to see that translators don't look highly at themselves or value the service they offer.
