Assistance with finishing Opencart 2.0 store and multistore

General information for the website: We are developing a number of websites based around the main opencart installation @ www.b2b.prodi.co.nz this store will be for our wholesale customers that will only see pricing once logged in so need a few finishing touches to the setup of the pavotheme extereme shop. We then want to run a number of retail stores the first being kingsofchrome.com. Once this is done and both parties happy we will look at doing the remaining stores.
Kind of development: Customization of existing website
Description of every page/module: current site can be seen at www.b2b.prodi.co.nz this site just requires the finishing touches of tidying up lines, upload of main images and tidy layup. The next site which will run off same admin and product database will be www.kingsofchrome.com this will need to be established (products and store loaded so just setting up domain to show website and carry out layout of pavothemes sportshop.
Description of requirements/features: tidy up layout and setup modules position etc
Specific technologies required: opencart
Extra notes: there will be a number of additional jobs if both parties happy in all we have over 15 domains that will all require some form of development and annual spruce up.
