I you can provide a direct link to purchase Adobe Connect for my organization

Most resellers will take credit cards and get you started, Adobe Connect | Strategic Partners.

Adobe took down the option for the monthly account a while ago, but there is plans to bring it back. But I suspect that a month or two wait is too long for you.

My recommendation would be to reach out to a reseller, you're welcome to contact me off forum at jorma[at]realeyesconnect.com, and see if anyone can help you get what you need.
