Hello Lana,
I'm John a professional web application developer. I can deliver an elegant website for your organization. Since you'd need to be able to update the website frequently, it would be ideal to develop such a website for you using a Content Management System (CMS) such as Joomla or WordPress. That way you won't have to worry about modifying HTML/PHP codes, or any codes for that matter. Updates to the content of the website would be via a user friends text editor and you can update media (photos, etc.) with ease.
Looking forward to delivering an elegant solution.
Regards,
John.
