I am developing PHP websites for past 2 years. I have developed 2 websites using CodeIgniter Framework till now and all of the m is totally developed by me. Since CodeIgniter is the new generation PHP MVC framework, it is better to use it in the production because of its high security features.
What the Seller needs to start the work
1. You should give a clear view about the website you want me to build for you Number of pages to build, Login system
2. You need not to clearly have the view of database if needed but you can suggest me some idea of it.
