An hour a day with anyone is unrealistic. Even an hour a week with any individual is a little unrealistic. If, on the other hand, you aim for an hour a day but split between a number of people you'll have a lot more success finding people to talk to. 

I am proficient but not native... :( I really need some french speakers to practise with me, I can help with the grammar but I don't have native British/ American accent... 

I meant, skype english conversation ( 1 hour/ day if you can) but you are not obliged ;)

For the moment i do 1h hour every week with an english speaker who want to learn french :

Hi!I'm interested about your demand.Thanks

Can you clarify your request more ? :P
