Know-How Exchange : Taglines/Names

You'll need to give us more details to help you.

Let's start with...
...where are you located?
...what type of clients do you serve? Located where?
...why do companies choose your services (instead of the competition)?
...why should your prospects care about "solid relationships"? Why wouldn't they care about translation that's accurate, effective, on-time, and cost-efficient?

OK I will try and provide a bit more meat on the bone:

where are you located? Spain

what type of clients do you serve? Technology companies including R&D, Telecoms, IT etc

Located where? Globally predominantly Europe and North America

why do companies choose your services (instead of the competition)? Expertise, Price and consistent service is the foundation. We try to know our customers really well and build relationships lasting years

...why should your prospects care about "solid relationships"? We don't believe in grabbing your money and running. We want to ensure that the customer is happy with the service and continue to come back

Why wouldn't they care about translation that's accurate, effective, on-time, and cost-efficient? Not sure what you are after here?

You say that your "core value is building stable employment for the employees through solid relationships with their customers." If I was looking for a technical translation company, I'd want a core value of quality technical translations with quick turnarounds. I think the tag line should reflect this (and Jay Hamilton-Roth's suggestions are aimed at this).

I almost like like "Quick & Accurate" but I am concerned that quick may not be the case. Let me explain. The aim is not to provide the translations as quickly as possible, but more in line with the customers requirement. I am also like the word quality.
