Hello,
I have just one question about your offer what do you mean by this:
"Have only access to SSH, need help to create web access admin credential, and help with up to date version."
If I am thinking right you can access just server running Confluence with SSH and not from its web interface and you need help to setup Administrator password for Confluence to be able to access it via web. You will also like to be updated with the latest version?
I am working for an Atlassian Partner company and providing expertise in designing Jira/Confluence for the enterprises. I have also experience with Atlassian High Availability solution called Data Center which is aimed to companies with more than 10k users.
Is your system already used in production or it is just a test system?
If used in production, what is the size of your Confluence user base (if you know this)? Do you maybe know what backend DB is used by this Confluence instance? PostgreSQL DBMS maybe? What Linux OS is hosting this instance? CentOS? What is the current version of Confluence you are running (on this depends upgrade path/methodology)?
If you do not know answers on this questions do not worry I can help you/guide you where to find them.
