Нужен специалист со знанием PHP 5.3, MySQL 5.5 и выше.

Для оптимизации запросов к базам данных и снижения нагрузки на сервер ищется специалист со знанием PHP 5.3, MySQL 5.5 и выше.
Есть работающий интернет-магазин. Примерно полгода все работало хорошо, и вот недавно пришло сообщение от техподдержки хостинга, что сайт заблокирован из-за чрезмерной нагрузки на сервер баз данных запросами вида:
