Schooling options in Stuttgart / Göppingen for my 5 year old daughter?

I have got an offer from a German company in Göppingen, I am from India and my daughter knows basic English. I am just wondering what would be a better option, to put her in a German school or an International school. The International School Stuttgart is way too expensive, is there any other cheaper option available for International schools? Are there bilingual schools available also?

The international school in Fellbach near Stuttgart isn't particularly expensive for a private school in Germany (and it's the only English language school in the area, as far as I know). Besides, Goeppingen to Fellbach is a one-hour commute (each way).
Depending on the age of your daughter, putting her in a German public school might thus be a good option - although she's likely to lose a year or so while learning German.
