I started to learn on accoustic too. it's true, the strings are harder to fret, and so when you switch to electric, it's like walking on the moon!
Plus it's almost impossible to do pull offs on the accoustic. You pretty well have to twang. You can also use accoustic to maintain your callouses.
My fav site for learning online lessons is;

and practice all the time.
