We have a Access 2010 database in Sharepoint web services that has parent/child issues, lookup issues, etc. This is all developed in Access 2010 with no hybride characteristics at this time. Do not bid on this project to translate to sharepoint. All development is in Access Services of Sharepoint.
I am an experienced Microsoft Access developer and very familar with Access Services 2010 on Sharepoint. I had done consulting for designing Access app on Sharepoint and will provide a sample db I worked on Access 2010 fully compatible with Sharepoint. Please see more details in PMB
