Steps:
1. connected to database
2. update BIDS_PROGRESS table --- copy all new projects to BIDS_PROGRESS from PROJECT table
3. get all projects that we haven't fetched bids yet.
4. determine how many projects you want to extracts their bids information
5. make requests, extract bids information and insert information to BIDS table
6. update BIDS_PROGRESS table, mark the project we have already extracted
