Well, why don't you go for your own domain,this is very important for directories..from now,using phpmydirectory
Why not consider getting some free hosting (one that has PHP and MySQL and preferably something like PHPMyAdmin), and then get a script such as PHPLD, and set it up on a paid for domain, so spend maybe $10 just for the domain, then if it's successful, back up the database and head to better hosting plans, and consider a script upgrade
