Edit wordpress / woocommerce online shop

Have bought a wordpress / woocommerce online shop (which has been set up to demo stage by Blue Host / Mojo market place). Need assistance in customising to our needs including adding postage options, payment options. and advising us on the SEO of each product (it has Yoast in the package), as we are new to this. We have started setting up 1 product & want someone to check we are on the right track with the SEO's etc. Would prefer 1 to 1 assistance - we already have a 1 & 1 online shop set up at present (but wanted something better in terms of layout / SEO etc).
