Data Analysis/Conversion

Greetings, I am looking for someone with good math experience to do a quick, easy two step process for me using existing data. I have a survey that was done using a scale from 1-10 and I would like you to take the answers (in a table and convert the results to a scale from 1-5). Basically, you would just divide the results by 2. The 2nd step of the project is to take the responses and convert them into a text delimited or csv file, or Access db, or mysql table so that they can be imported into my existing table. You would be supplied with the 2 tables for comparison purposes. This should be easy if you have experience in analyzing data and/or writing scripts to import data from a table into another table. Ideally, you will have data analysis experience along with some php and/or mysql knowledge.
