I hope the Expat Arrivals forum will help you connect with others who have lived and worked in Indaiatuba.
You'll be happy to know that Indaituba is only a 1 and half hour drive from Sao Paulo, so you shouldn't feel too removed for the city life. Also there is a direct bus from Indaiatube to Sao Paulo.
Take a look at our Brazil Country Guide. While it doesn't focus specifically on Indaituba it does contain lots of useful information for expats moving to Brazil. It covers topics such as Work Permits for Brazil, Cost of Living in Brazil and Healthcare in Brazil. It should certainly help you with the move.
Best of luck,
