Hello,
The site will not allow us to post a bid above $1500. We can accomplish this project with perfection, but it would be in the neighborhood of $6,000 - $10,000. Other developers may think this can be done inexpensively, and still done correctly. We believe this is sorely underestimating the amount of effort required to consume web services and keep multiple data sources in sync. Data integrity and database performance will be our chief concerns on a project of this type.
We are very interesting in seeing your project is completed accurately, masterfully, and completely.
Please let us know if you would like to discuss the specifics further with us.
