Cargo Transport ex Mariel/Havana port to Trinidad

Hi Cuban members !

I am married to a cuban and have the Cuban Residence Permanente since March this year. Now I am planning to ship my personal effects , which will arrive by end October.
Only problem is , is that shipping line can only take my container till quay port Mariel/Havana. So I need transport (after customs clearance) from Mariel/Havana port to my house in La Boca/Trinidad Prov. Sancti Spiritus. I have contacted many companies , but all only arrange transport to Havana or area Havana , and they all advise me to take a local transporter from the area where I live.
Sadly enough , my husband (is Cuban !) and me , we cannot find any !!!
Is there anyone who can help us or knows people to contact about this ?
