Is there a global Third-Party freight forwarding service for small packages?

I am still starting out with my business and I got a request for sample designs so I need to ship samples to a few potential clients across a few countries in the EU but I don't have a business address yet and I don't want my own address to be visible. I want things look as professional as possible. I found large scale freight forwarding but they don't offer the smaller package forwarding option? I have 11 little boxes and I'm UK based - anyone have any ideas for me please?

I found: Omni Logistics and Worldwide Express - is there a smaller boutique kind of 3PL out there?
