Ask HN: Advice on next step for Expression in Design

Hi all, My brother has been running a successful website business for a while now: http://www.expressionindesign.nl/. Amongst other things, he caters to the needs of local businesses in, and associated with, The Netherlands. He's got a decent portfolio now (http://www.expressionindesign.nl/portfolio/), and I mentioned to him that the folks here on HN are probably the best to ask feedback on what his next step should be to ramp up the business. Specfically, if anyone has gone from the stage he is in to accelarated growth, to provide websites to restaurants, events, venues etc., I'd love to hear your advice. Anyway, hoping someone can weigh in with their two cents so that my brother can strategize as to what his next growth channel should be. PS: This is my first submission, so I hope I haven't broken any cardinal HN rules. Please correct me in case I have.
