I have been freelancing for a few months and all ticking along nicely. However many competitors offer a wider range of skills than me, and to become more marketable it would help if I offer those skills too.
I don't really have the inclination to learn these new skills (would rather stay as an expert in my fast moving field) but would if I really had to. Is it reasonable to advertise these skills within my portfolio and when I receive work, field it out to trusted freelancers and take a cut myself?
I've only worked in corporate world so not sure if this is considered acceptable and whether freelancers would be happy to have this kind of arrangement?
