Yes, absolutely for consultancy though, and not an actual company. It's like someone entrusting you with millions to network stuff together, that doesn't mean you get the millions.
I'm in that dilemma at the moment. Pa's business is swamped with work and can only accept a very small proportion of contracts/tenders. We literally lose hundreds of thousands weekly. As much as it's tempting to sub-contract and do something about the sheer, overwhelming demand. I made a conscious decision to not do that. Pa's unwell at the moment to make business decisions. If you start sub-contracting, you develop a consultancy reputation, and it's not viable long term. For a quick buck up to a few millions yes, but not in building a company and legacy.
Over the years we've run into lots of requests from consultancy firms asking us to do the work like a CBO doing work for an NGO, just because they won the tender for their "business solutions, wankerish, talk, talk, consultancy, prowess" but since they have very little idea on the reality on the ground, costs, they go bankrupt quite easily. It's not a solid source of income.
