Build an OPC HDA client & server in VB.NET

Please read everything before responding. • Build vb.net DLLs which can function as an OPC (OLE for Process Control) HDA client & server each (the DCOM version). Support full functionality of OPC-HDA. The OPC-HDA Server will work against a MS SQL Server database. The DB schema will be provided. Deliver OPC HDA client first. • A test application that will work with some Historian that supports OPC-HDA. Allow us to test the finished solution with it also. Must specify the Historian intended to be used. • The DLLs must not just be the examples downloaded off the some web site which don’t have the source code. • Need full vb.net source code for the internal part of the server & client. We need this source code in case we have errors or need to do optimization later. • It can have dependencies on PUBLIC and FREELY, UNENCUMBERED AVAILABLE libraries if necessary. • Works with latest .NET framework & Builds in latest MS Visual Studio. More info on OPC may be obtained from OPC Foundation website. You have to provide training to us for at least 8 hours to explain the coding topology-structure made in the project & also help encapsulate it into our code project successfully. The budget is flexible. Complete source code with detailed documentation for this project, need to be submitted on daily basis. The code & all deliverable will become our property. Please specify your team's hours (in GMT) when they will be readily available via phone etc. We expect a week time of delivery from you after the award or specify the time. Provide us with rough milestones (if any) tied to payments. no upfront. Delays will cause problems for our project. DO NOT PROVIDE ANY IRRELEVANT INFO IN YOUR RESPONSE.
