Hello,
welcome on SEBLOD.
I can say YES, with "Joomla + SEBLOD" you can do all what you need.
It's only depending on your knowledge on those two applications, and on some web languages (php, css, javascript, mysql,...)
"SEBLOD" will help you a lot, for the biggest part of you project, but like each time, there is always the custom part, where majority of people can't go further without knowledge on developement.
Best regards.
Lionel
