MYSQL Advance Query

We need a MySQL expert to execute the following query: We have two tables, one for customer information, and one for the orders placed. Users table structure (only needed columns): user_id, name, lastname, mail Sales table structure (only needed columns): sale_id, user_id, sale_total, sale_date, sale_status What we need is a query that returns name, lastname and mail from the customers that placed their last order within the 2008 or earlier (and never ordered again since then). Also, the order_total must be over "100" and the sale_status must be = "4".
