Script for reading .csv file

Can someone please help me to write script for following scenario :

1> script should read a input .csv file of format : EmpName, PF, Leave, Basic ,HRA
2> another config file ( may be again a .csv file ) has format EmpName and EmpID
3> script should read another config file for each EmpName in the input file , to find the EmpID
4> After finding EmpID from config file, all records need to be written in 3rd file ( output file ) with format : EmpName ,EmpID ,PF, Leave ,Basic ,HRA

Here's something to start with.

nawk -F',' -v OFS=':' -f emp.awk conf.csv input.csv

NR==FNR { a[$1] = $2; next }
$1 in a { $1=$1 OFS a[$1]; print}
