Split ready parallax website into diff pages for SEO

Hi

I have customised a parallax website, gallery, using a template I purchased somewhere. I'm happy with the way it looks but need someone to split it in separate pages, as Google will probably get the hump with it being so top heavy, and I fancy using h1 per url instead of one h1 for all of it.

Apart from that I need someone to give my script a once over in case I'd missed something obvious from SEO point of view. I'll have all the alts done and descriptions similar but not pasted from alts on the pictures, and things like that.

I'm on a budget and looking for a reasonable quote as, although it looks reasonably straightforward, I'm a bit scared of doing it myself.

In terms of what's in website, you are welcome to have a look at my old one that's up at the moment, which is a bit of a mess but will give you an idea, anyway, new one will have less pic otherwise the content is v similar www.lucandlucyscupcakes.com

Thank you
