Fighting for our lives here, need customers asap (I will not promote)

What's the most effective method of gaining clientele quickly? Anyone have experience with sales through LinkedIn? We’re a small bootstrapped team based on the west coast of Canada and we're fighting for our lives. We've been operating for a year now but only went fulltime official this past November.  I've really lucked out with having found such a talented team that's enjoyable to be around and is committed to making the company work - they go above and beyond all the time and it actually makes me a bit misty thinking about the fact that these awesome humans are willing to fight it out beside me to help this business survive, in spite of the stress and the struggle.    This winter has been rough. I think it's a combination of: * the time of year. * doing business in Victoria (our base) is difficult at the best of times. * the political climate in Canada and the tensions and uncertainty with US trade (everyone's hunkered down waiting to see what's going to happen). * the fact we're brand new and unknown, and we've never had the budget to do any sort of paid advertising.    Maybe I've got the classic founder's delusion but I know we've got an overabundance of skill and work ethic and the regular clients we do have really enjoy working with us, so we can make this happen for sure (delusion?). We just need MORE clients, and fast. We need enough work to fill out the extreme peaks and valleys and regulate our cashflow. We've been trying anything we can think of to generate sales: generating a leads list of businesses we already have a good relationship with and contacting them, cold calls to other businesses, leveraging our personal networks, helping people out through Reddit, Upwork (which was not great), Instagram/Facebook posts… we even put up posters around town haha   Today I read a comment about someone offering commission-based sales through LinkedIn which sounded intriguing. I'm very new to LinkedIn and haven't quite figured out how to use it properly other than to make connections. Is this a viable route to generate sales quickly? Is commission-based LinkedIn sales a thing you've heard about and is it worth it?  Any insight, help, comments, experience are greatly appreciated  <3
