Hey Moises
Yes ask a local notaire but unless you know one, preferably try to find an "office notarial". This is just several notaires working together so that they each specialise (immobilier, family, business, etc). You can't negotiate the fees are this is fixed by law.
You can, in addition sign a "mandat de vente" with a local "agency immobili?re" but make sure not to sign an "exclusivit?" and put them in concurrence by signing with several, say 2 or 3 from different groupements (FNAIM and the like). Negociate the fees to no more than 7 %.
Hope this helps.
Keep in touch
