我諗住講法文冧你冧到你就俾評啲嘅價錢我

Hi

I need help with a translation. I've been asked to translate the following sentence from English:

"I thought if I spoke French you'd feel moved/touched to the point that you'd give me a cheaper price". I've translated it as follows:
我諗住講法文冧你冧到你就俾評啲嘅價錢我

Does this sound right to a native speaker?

Thank you
