We operate entirely in the US and UK, and do not offshore anything. Offshoring is fine for others, but it's not for us.
We do most of our work offsite, but occasionally work onsite or travel when our clients can benefit from that. We generally communicate with our clients by phone, email, and web conferences. We live and breathe on the Internet.
We're a very lightweight and efficient group, and don't carry a the kind of baggage or overhead that a sales-heavy agency requires. No retainers, no hidden fees, etc. We focus on the work, not selling more work. You only pay for the work we deliver.
