Leaving El Salvador and need tramitista y agencia de carros

I plan to pack my personal things and go to the Dominican Republic.

I have an apartment in San Salvador, but I travel most of the time in Central America and the Caribbean for work. The DR is a better location for me.

I need to sell three vehicles and prepare personal items to ship via container to the DR.

Can anyone recommend an honest, reliable auto sales agent and a competent tramitista. I deal with tramitistas who know about commercial stuff, but they don't seem to know anything about shipping personal stuff.

Appreciate any help. Just found this forum. Wish I had known about it years ago.
