I live in Mexico so I speak Latin American Spanish but let me explain why that's completely irrelevant.
The most important thing to master in Spanish is STRUCTURE which is the exact same for all Spanish regardless of the country.
For example, the correct use of Pronouns or Por vs. Para or Ser and Estar are the same in any Spanish speaking country. The structure of the language doesn't change... only the accents & decoration.
Once you have structure in place it's such a simple task to add in the finishing touches afterwards to match your target country.
Honestly, it would really be a shame to disregard this course simply because you believed you needed one specifically for Spain... or Argentina... or Mexico!
It'd be like insisting on an Australian English course simply because you intended to live in Australia. It's irrelevant. What you need is correct structure. Period.
