Moving to el Salvador. Apply for residency.?

Someone I am engaged to just got deported/ is being to el Salvador. I'm a us resident and want to leave here. I've sold everything. I have a place to live once I get there. I need to be there in 2-7 weeks. I know I can get my pport expedited and have it In 2 weeks... Now the visa... I see I can get 30 up to 120 days. I want more. To apply for residency it says I need to live there 5 years. How can I do that with only 120 day stay? Can anyone recommend a good lawyer to help In Virginia? Can I rent an apartment there with my pport? Drive?
