Ahh...this brings to mind my journey to South America back in the late 80's. 10 countries, 10 weeks, and a whole continent littered with broken hearts...LOL. I was 21 years old, thin, blond hair and blue eyes...and them girls threw themselves on me like you wouldn't believe...LOL
And there was this Australian girl who took a liking to me in Rio...
Ahh...those were the days.
Would I think of doing such a thing now, if I was suddenly single?
I would say not. Just too many variables that have the potential to spell disaster. Language difficulties, cultural barriers, lack of common interests, etc...all of these are not generally conductive to long-term relationships.
My advice to you would be to just be "on the lookout" so to speak, and meet as many individuals as you can, as opposed to going about on a planned mission to bring home a new wife.
And my real advice to you is to make every effort to travel for a while. If you could have someone take care of your mother for a spell (your brother perhaps??), I'd highly recommend that you take an extended road trip around the USA. Go visit Yosemite - and be sure to stay in the tent cabins at 9000 feet, where you get to have fresh trout in a group tent with folks from all walks of life. Take a ferry across Lake Michigan. Go visit a sustainable community or 2. Go chase a hurricane or 2. Have an adventure.
The reason I'm suggesting this is that it's more important to put yourself in situations where a chance encounter is probable, if not likely...I've met so many amazing, interesting people doing things such I've described above (except for the hurricanes...LOL). And I think there's someone out there that could make a great fit for you - you Just Never Know.
To put it more simply, if you try to "force" a relationship, it most likely will not be the real deal. Being single is better, IMO. However, if you make a "wish" for a relationship in your head, but don't make it your primary, everyday objective, then the door is open for that chance encounter that so often results in life-long marriages, soul mates, etc. But those have to "happen"...those are the kinds of things that come looking for you, as opposed to the other way around. You do, however, increase your odds greatly by getting out there and having a chance to meet people.
But then again, those Brazilians are mighty sweet.

Nowhere to run, nowhere to hide...
...and the meek shall inherit the Earth!
