Suggestion for VB Forms in Version 4 to Version 8.0

Hello, Group:

Our company used version 4 for sometime and had many customizations
done. The VB Forms in version 4 aren't compatible with version 8 since
version 4 used Foxpro, while version 8 uses VB.NET. Can somebody
recommend a software package or consulting company (besides Epicor)
that can translate the Foxpro language to VB.NET?

Much regards,
