Hello, I am very interested in this project. My name is Jenny.
I went through your description very carefully. Thank you for the clear requirements.
I am very familiar with Warp framework. Although your template is not Yootheme template, Warp is their framework and I have been their member for years and used to work with all versions of Warp.
I am familiar with JoomlaCK Editor as well. I can't say it is the best editor, but definately it is very popular. I know all its functions.
DOCman is not the best choice, I agree. I would like to see what exactly are you using about and I will be able to suggest something else.
I will be happy to write instructions, I am very good in teaching :)
Regarding the site security, we might need RS Firewall. It has a lot of options to prevent attacks. To prevent somebody to reach the files we can think about changing the URL's or similar.
No problem to move the site to another hosting, its size is really big but I don't think this would be a problem.
To upgrade the Joomla version and to move the content I use the help of SP Transfer for upgrading from J2.5-J3.x.
I can be available during your working hours on Skype.
The place here is limited, so if you have any questions, please let me know.
I am a Joomla specialist (experience - 10 years in Joomla development).
I'm a moderator of [login to view URL] and joomla-bg. forums.
[login to view URL] (Responsive, upgrade)
[login to view URL] (Warp, responsive )
Best regards,
Jenn
