First thing that platform should I choose? I think the easiest way to build a webshop is to use a CMS system. Systems are systems. And these systems are easy to use and simple to customize. I advise you to choose WordPress. Why? My customers can't use the majority of the CMS systems, although I'm a software programmer, so I can use any CMS system easily. My experience is my customers can learn WordPress in a brief period and it can be used by them easily. And you'll see at the end of the article WordPress is very user friendly.
Finally, secure your wordpress site will also tell you that there's no htaccess in the wp-admin/ directory. You can put a.htaccess file into this directory if you desire, and you can use it to control access by IP address to the wp-admin directory or address range. Details of how to do that are easily available on the internet.
The one I personally recommend, and the stronger approach, is to use one of the password creation and storage plugins available on your browser. RoboForm is liked by people, but I think after a free trial period, you need to pay for it. I use the free version of Lastpass, and I recommend it for those of you who use Internet Explorer or Firefox. That will generate secure passwords for you.
Keep your WordPress Installation up to date - One of the simplest and most valuable tasks you can do yourself is have a peek at this site to ensure that your WordPress installation is updated. WordPress gives a notice in your dashboard to you, so there is really no reason.
Now it's time use this individual's name and identity to present as your buddy and to register for a Facebook accounts. After I get it all set up, I'll be telling you posing as your friend and asking you to be friends with me on Facebook (or Twitter, or whichever societal site).
Just make sure that you can schedule, and you choose a plugin that is current with the current version and release of WordPress, additional info restore and replicate.
