Hi Ram and welcome back!
I recommend InfoPath 2007 in conjunction with a Web Service. Qdabra provides a free trial of it's Web Service. This solution has helped many many companies quickly develop data entry solutions. Check it out: http://www.qdabra.com/en/products/DBXL.aspx
Best of all: no programming required. Yes, we help Microsoft fulfill the promise of InfoPath: paving the last mile to your data-entry doorstep.
