Hi,
I can help you to make your website bilingual (French, English). I have read the description you posted and I can tell you that I have the necessary skills, especially in Laravel, to do this project.
However, you have mentioned in the description some improvements that need to be done on your website but you did not specify them. Without knowing these improvements, I cannot estimate the time needed to realize your project and consequently the budget. I propose a rate of 12 USD / hour.
We can further discuss your project by private chat.
Kind regards.
