Okay, well... I am wanting a skill for skill, or skill for product exchange!
I can SEO websites
(get them ranked higher in google - brings more traffic, more sales/punters etc) - Its what I do for a living for corporate clients etc...
I am pretty new to the bike scene, and would be into swapping my skills for either some bike servicing (ONLY people that know what they are doing) - or bits for my SV650 curvy.
Bear in mind I usually charge a fair bit for my services - but not too bothered about that, just thought it would be fun and a good way for us to get things for free! - see my sig. (email link)
Cheers! - hope you guys don't think I am a nutter! - if in doubt, google this:
link building packages - this is my main service...
1,950,000 google results, I am at no.1 
It does take some time for these results, but I can certainly give a decent boost to your rankings!
Cheers,
Mike
