General information for the business: we are internet company
Kind of development: New program from scratch
Description of requirements/functionality: This could be run as a stand-alone software or a web-based software.

Please provide to us the following materials if available - we need to see your previous work on web or see some case studies or any other relevant information that proves your expertise in this field.

The client has the complete and exclusive ownership, intellectual property right and copy right except for legally using open source libraries or programming the code. But the contractor should provide original links and the code.

The Script based on Google map should be able to capture the following information/data,
1. The search scope should be worldwide region (every country and every city, except North Pole, South Pole and the ocean regions).
2. The program should be able to find results based on our keywords.
3. Since we have many keywords, the script should allow us to input the keywords list file (.txt).
4. The data for each of the results should contain name, address, other contact information, website, image URL, business hours, and coordinates (if possible).
5. The output data should be MySQL.
6. There should be no limitation for results!

The Script should not be too difficult to use. It would be better if it has a clear UI.
