Neatening up an account

hello,

I own and run a Day Service for adults with disabiliities. I absolutely love my job!!! over the last 2 years we have grown organically and now have 3 locations accross hampshire. Our social media presence has grown with us, but it looks a little messy.

From what i understand, the 3 pages can be setup a little nicer. essentially having a main page, and then "sub pages" leading off from it.

I dont have the time and understanding to do a great job... so i'd like someone to give me a help please..
