There are over £3000 of sign ups and an easy £1000 per month to be made, and that is not unsubstantiated claims.
It can be time consuming, but even if just for the start, it is definitely worth it. I work in finance in the City and still make time for it (although am selective over which offers I do so only get about £400-600 per month).
Anyways pop me a PM if you want some more information on it.
