Hi Howard,
Thanks for your kindness.
I made some calls and found out Moodle Partners actually serve more than Server.
I should had to know this then I do not need to worry about developing so much.
Cost seems expensive as it is more than $1000 per semester.
The benefit is I do not need to worry about server at all and they keep backup and can give me some advice.
Still I am concerning the price because our user will be just 300 per semester.
Income will be outcome.
If you know any partner who can provide hosting service with some $40 up to $60. Then we can try at least.
Thanks
Regards
Kim
