Brazil is a difficult country due to its complex tax structure. However, Brazil is huge in software development and tech ventures; so I would recommend reaching out to some PEs or VCs that already invest in this sector and are open to save some bucks in office space by leveraging on the coworking space you offer. Also, there are many US companies that have just sales individuals in Latin America or Brazil; so reaching out to those companies through a marketing campaign linking US companies with US Realtors offering a guaranteed space with their initial investment could increase your cash flow to start building up offices. Hope this helps.
