Inferential statistical analysis for survey

I am a professional researcher investigating language use in bilingual families. I have recently conducted a questionnaire study with about 500 responses. The questionnaire asks around 15 questions relating to demographic information of the participants, and 5 questions relating to language use in these families (i.e. language used with children, language used with partner, language children speak with each other etc.). I am able to do all the descriptive statistics in relation to this study myself, but I would also like to run some inferential statistics and turn this questionnaire into an article. What I want to do is to analyse the relationships between the so called predictor variables (i.e. country of origin, if the mother or father is the minority language speaker, municipality lived in, number of children in a family, education level etc.) with some outcome variables (i.e. the five questions relating to language practices). I have no real background in statistics so I can't do this myself and I do not have the time to figure out how to do it. I need someone with a statistics background to tell me what to do (or do it for me) and then how to understand the results. The questionnaire results are in an SPSS file. I am not asking for anyone to write the article, only to do the statistics.
