Thing is, I'm sure no-one would bother if you started a thread telling folks what you do and where you work but opening a traders account might help especially if you intend doing a lot of Micras.
You get your own section, banner and if you have leaflets printed the club will put them on their stand at meets etc. The whole point of making folks pay for a traders account is because it will lead to more business.
At the risk of sounding smug, we are out the door with bulging diaries and workshops. Many garages in our area know we specialise in Japanese cars and welding and are happy to send their cars to our workshops. But thats because of word of mouth and years of doing the shi... doing the jobs no-one else wanted or didn't think were worth doing. Word of mouth and willing to do a good job for a fair price is far more likely to get you work than a cheeky thread on here!(Y)
Anyway, you have kinda started a thead about your services anyway. Why not tell everyone how they can contact you and what you can offer?
Starting a blog or thread about your K10 lets you show off your mechanical skills with pictures etc. Becoming a member of the club means you can read and post on the 'How to guides' section too.
