Panama Work Permits

Hello All,

My Company is seeking work permits in Panama city.  We have 6 crew members travelling in April of next year (2017) for 5 weeks.  We do specialty glazing and will be constructing the storefront for Victoria Secret at the Multiplaza Pacific Mall. 

I am having difficulty finding specifically what we need to apply for work permits, where to apply for these permits, and costs / time associated with acquiring these permits.  I understand we need to apply for these permits through the Ministry of Labour, and there are several options for these permits, but how do I know which to choose? 

I am assuming we will be applying for specialty workers permits.  The entirety of 10% of company vs 15% of specialty company is confusing me.  If anybody has some concrete answers for me as far as how I apply for these permits, which permits we should apply for, and what we need in order to apply, I would absolutely I appreciate it.  Thank You
