The site is simple and has a clean interface - but its a little "too" clean.
There are no examples of your services... no before/after images of sites you've translated or pricing structures.
Step 2 of your point of sale says "Confirm instant quote
If you agree with the price and time given, you can proceed to the order page immediately"
What if the person doesn't agree with the price - is there a sales tool in place to haggle the price? (such as a "buy this service now at this price and get your text translated into 2 additional languages of your choice free")
Do you have value added service in place? Meaning that simple translation services aren't enough. If you are (and I presume you are) offering the service to translate tours for adult paysites, then some of the text will need to be embedded into the actual tour images and my guess is that the company buying your services doesn't have the language setup to do this themselves.
You could also set up a corporate pricing structure and be on retainer to generate consistent monthly revenue.
Just some quick thoughts - you have a site that offers value and a needed service and I hope it does well for you
