ask around some local computer shops, pc repair and building pcs to spec can be a bit more rewarding but still not massive money involved, i started 12 years ago for a small company building computer for government agency then i started building and configuring most of the computer for a company called special reserve and finally went on to supervising a group of technicians in an IT insurance claims department where we got to build/ repair/configure and fault find a wide range of computers and laptops, this was rewarding work but even in a supervisors position i was on 17k and the technicians were on around 12 - 14k as stated.
Remember though it is not all about the money at first esspecially when you have no experience, dont expect to walk in the dream job earning loads of money as thats just not how real life goes im affraid (although i wish it did).
