develop a software of turnkey solutions

I hire special services to develop a software of turnkey solutions to offer to my clients for them to create by themselves their own ecommerce web sites with their own admin panel. My clients are people who sell things by internet, most of them through drop shipping but they want to create their own websites by themselves with all the key feautures included. This software has to tour my clients from to choose some templates until to choose their secure payment gateway (Paypal) that they will offer to their clients. There are other suppliers of turnkey solutions worldwide, however, I want to do it in spanish for the spanish spoken countries clients for them to set up their own businessess without attending to a programmer or webmasters. I want to offer a website (like 1&1) for them to create in my website their ecommerce websites.
