You should start your teslas upgrade right away. Everybody keep them for last because they take so long and end up skipping them.
I alternate my upgrades : splash/point/tesla/elixir upgrades.
splash : mortar/wiz tower/xbow
point : cannon/archer towers/air defense
If your walls are not maxed, this should give you the time to upgrade tons of them. Just keep one builder available for walls (if you have 4 builders). If you walls are maxed, upgrade 2 teslas and occupy the other builders on collectors. Not that it's that helpful, but at least your builders will do something and they will become available faster to dump gold in your walls.
Good luck
