Hi there – try posting on social media groups/meet-ups in Christchurch e.g. Facebook – and /or think about why they need to be based in Christchurch – there a few of the advisors/experts who are excellent at social media like Nick McDonald who could help. As Craig says, what industry, can you explain a bit more. Andy
I am happy to help if I can, please drop me an email to firstname.lastname@example.org. if you wish to set up a chat. I am not based in Christchurch however might be able to point you in the right direction if necessary, or just lend you some advice.
Also one option to find a handful of local suppliers is to go to http://www.bark.com and plug in your details. You should get contact back from up to 5 local providers.
