Regularly Update Webpage with Wordpress CMS - Urgent.

Hello world, I'm searching for a reliable and trustful person who can regularly update a webpage with wordpress [login to view URL] have to be available to do it right now. You should know what you are doing because whenever I try to update it myself I noted some graphic errors occur. You should fix this problem. You should be able to make simple changes on the page: maybe add some images, add new text - sometimes change the lettering, add news, etc. This may be a long term relation: maybe you will update this page from time to time. In this project I'm giving preference to a brazilian or portuguese guy because the webpage in question is in portuguese. Best, DB.
