In the absence of more helpful & practical/direct advice to your plight than I give here sarahwatton, may I suggest you go in to the 'SEARCH' facility & check out the archives, do a search on "Moving to the DR", "Relocating", "Finding a home/rental place", "Jobs in the DR", "Cost of living" ........... & all the variations on these that you can think of. That way you will learn quite a bit more about the country & the difficulties you are about to encounter by moving here!
Is it worth it in the end???? You bet it is, .......... IF you know what you are doing & can adapt to the totally different lifestyle.
Can you survive here on your savings for 6 months whilst looking for a job? (You might not find one immediately & IF you do, it will doubtless be a low paid one because ALL wages are low here!!). I would suggest 6,000 Pounds Sterling (US $10,000) would be the minimum required to last you 6 months!
Once you have studied, read & inwardly digested the information held in the archives (two weeks solid reading at least!!), come back with more specific questions AND quite a bit more invformation about yourself (Age, marital status, children, experience, number of times you have visted the DR, REASON for wanting to come, .............) & I am sure others will join in with me to answer your needs!
Best luck ~ Grahame.
