Internet research - open to bidding

I am in a rush and don't have a lot of time. I need to find a company that can implement a SMS Service to a Customer-Realationship-Management (CRM) tool based on Siebel (by Oracle) We need to send and receive SMS with this tool and prefer Companies that can provide service in central america (including Costa Rica, Honduras, Guatemala, Panama, El Salvador, the Caribbean, the Dominican Republic and Nicaragua). Could you find out some companies, so that we can ask them for further details until Tuesday 5am, Costa Rican Time? I would be very thankful. Kind regards and greetings from San Jose, Tom
