Get a really good business card. Not just really good but really high quality.
My business card is the thickest business card (not stupid) I have ever seen. It is matt laminated, double sided and does the job.
People will pay no attention to a standard one and it'll end up in the bin.
Make sure all your business profile literature is top notch.
When I started trying to gain commercial I put together a portfolio, basically a paper version of the old website, decent & current cover letter and hand them or post them out.
I bought a laminator, ring binder, clear covers and hard card backs, filled it with the relevant information.
Got a £20 000 a year works, did it for 4 years - not a bad return.
Will be going back to this as a point of reference, once the main website is updated.
All the best
