Personal experience: The advantages and disadvantages of being a middleman

Have you ever acted as a middleman yourself? If you have, you have probably come across both positive and negative experiences and you can probably add to these lists. And please do that in the comments - I will update this post whenever there's something added.

Advantages of being a middleman

• You don't need the exact skills to get the job done, but you do need to be comfortable in the industry you work as a middleman.
  
• Only the sky is the limit in searching for the jobs. If you can work in multiple industries, you can search for projects to take up pretty much everywhere - both industry and country-wise.
  
• It doesn't require any remarkable initial investment. However, it would always be good to have some backup money in case some jobs go to hell.
  
• You are not forced to work 8 to 5.
  
• You can take a nice middleman fee, depending on the project, anywhere between 10 and 90%.
  

Disadvantages of being a middleman

• If something goes to hell and you don't have the skills to fix them, you're in trouble, and you need to spend your own money to get things fixed.
  
• You are responsible for the subcontractors work.
  
• Finding the right people for the job is never easy. There are two main factors to consider - firstly, can the people get the work and secondly, are they trustworthy enough. And of course, all that for the right amount of money.
  
• While you are not forced to work 8 to five, you might end up working 5am to 11pm.
  

Enough for now. Tell me, what are the advantages and disadvantages of being a middleman in your opinion?
