Hi Ulka,
There's not a lot of options that I'm aware of.
1) You could see with the University's Maison des Langues who do a DELF (Diplôme d’Etude en Langue Française), see Unfortunately the MdL website is all in French, which isn't helpful if you don't already speak French!
2) The other option would be to check the small ads of Le Quotidien or the JIR newspapers (see for example), where there are generally people advertising lessons. If you don't see anything you like you could post your own ad.
HTH
