editing android app database

I am looking for a freelancer to help me with editing an Android app database. The database uses SQLite and I have specific changes in mind that need to be completed. I need this project done within 24 hours, so I need a freelancer who can work quickly and efficiently. The changes will involve optimization and making general fixes as needed. If you have experience with Android app databases, please let me know. If successful, this could lead to further work in the future.
