I'm well-versed in python, php and Java and can write a script/program in any of these languages in the following areas:
=> Database Interaction (mysql/postgresql/sqlite/sql-server).
=> Database migration or backup scripts.
=> Web scraping or crawling.
=> Linux utilities (file systems interaction, cron jobs, etc).
=> Network utilities (Remote ssh/scp/sftp data transfer).
=> Remote Message Queue interaction (Need detailed info/docs about MQ architecture).
A single gig gets you a script with limited complexity, and doesn't include integration testing or deployment. More complex scripts and deployment on linux servers will involve extra cost.
