2 SQL Querry optimization and improvements

Our primary service is to rent mobile phone lines and we need to audit the phone bills that we get to see that the mobile operator is charging us correctly and also need to bill the end users. We have stored procedures that create both the audit and the re-bill reports on excel but we need to add a few feilds to the reports and make some other improvements like try to shorten the time that the current sp takes to finish and generate a report. Our objective is to start with VERY simple task so that the developer can gradually become familiar with the DB to then continuously make new reports, improvements etc. Our current SQL sepcialist is no longer able to do freelance for lack of time. Please bid for this simple task only if your looking to do ongoing work because it will take some time to become familiar with the entire DB structure. There are 2 basic tasks 1) create 3 new columns in our current report - We will tell you the name of the field and we will tell you the name of the fields that need to be added to generate the values that go in these new fields. This is something that our current SQL specialist could do in CONSIDERABLY LESS THAN 1 HOUR. Its VERY BASIC CHANGES with detailed explanation to complete the task. 2) get our current sp that takes about 20-30 min to finish and optimize it so that it runs in 1/2 the time or less. I have no idea how long this would take and its not a critical task that we need, its more to test the developers ability to improve what we already have. Its ok to just bid on item 1 if your not comfrotable estimating a value for the service without knowing more about the stored procedure to be optimized.
