To bi-fold, or not to bi-fold...

Wanting to get an idea/rough quote on how much bi fold doors would cost (supply and installation) to install on our gaage. Looking for cheapest bi fold door option available, nothing fancy as garage is being converted into extra hang out space. Have included photos below. Measurements for ONE side is approx 2640 x 2180. Wanting the bi fold doors to fold right accross to the other side (so I it would be accross the above measurement x 2?)
