Well, I have the native English speaking portion you are looking, but I am in the States. I work all sorts of strange hours here, which should translate fairly well for you in the end.
The number of hours required may be substantially less, but I left it a little high due to the different data types available in MSSQL versus SQLite. You also didn't mention the amount of data, but I have quite a lot of experience with ETL and making the conversion shouldn't present any problems.
PHP is actually my strongest language, but Python can certainly be used.
Looking forward to hearing from you.
