I am a member of BNI, a professional business referral organization. This is a group of business people I know and trust and can vouch for their integrity and the quality of their work.
You may not need any of their services at this moment, but if you ever do then please just follow the link to their website. The team I am a member of is Paragon in Blackheath.
We meet on a Wednesday morning for breakfast and if your trade is not represented and you like the idea of receiving lots of new business then let me know and I can arrange for you to visit us one week.
