Fiber Optic Internet Connection / Small or Shared Office Space

Thank you all for your excellent posts regarding py they have been extremely helpful!

I have a unique question.  Internet plays a vital role for me when living offshore and I've noticed on another thread the py providers.  From what I've been researching you can get a line as fast at 15mbps but the costs are simply outrageous.
 
I need at a minimum 3mbps down/ 1mbps up true international speed so this means when I do a ping test to a server in Chicago or NYC I'm getting the above results.  I usually find packages around 10mpbs+ are the only way to achieve the above mentioned.
With that said I'm not willing to drop $1500 a month on a 15mbps line, does anyone know of either

a) High speed fiber for 1/10 of the cost as shown above in Asuncion

b) Shared high tech offices / complexes with these internet connections and contact information regarding getting leasing space?
