business startup.

I have just started up my own electrical company, but the startup is as expected, very slow. I have a few different marketing strategies so far. this is firstly, to market myself on facebook. secondly via the community with business cards and ta;ling to friends and family to refer me. lastly I have also "partnershipped" with a long standing Electrical supplier and training provider as their "go to" electrical contractor. though I have not signed an MOU as of yet, this will be happening in the near future.

Also since they are an electrical training centre, registered with MERSETA, EWSETA, DOL, they are looking at bringing me on board as a facilitator for the solar green card training.

just wondering if there are other things I could be doing in terms of trying to bring in "immediate" cash flow. by immediate, what other methods of "selling" my services would be effective?
