I feel like there has to be people out there working in a similar field as myself (or who at least know the trade) which I can hire to help boost my business. I wasn't able to find such thing for small a Freelance engineer, but more at a corporate level. This usually sounds like mumbo jumbo, to be talking of vision, mission, etc. and all those corparate words, when people who revise my proposals are likely to be engineers.
