Emit Mapper Flattering and property name mismatch

How to map User class to UserModel class using Emit Mapper?

    public class User
    {
        public Guid Id { get; set; }

        public string FirstName { get; set; }

        public string LastName { get; set; }

        public IList<Role> Roles { get; set; }

        public Company Company { get; set; }        
    }

    public class UserModel
    {
        public Guid Id { get; set; }

        public Guid CompanyId { get; set; }

        public string FirstName { get; set; }

        public string LastName { get; set; }      

        public IList<RoleModel> Roles { get; set; }
}

There several problems:

I need to flatten the object such that I will have CompanyId instead of the Company object.
Company object has property Id, in the UserModel I have CompanyId which corresponds to the company id, but property names do not match.
I need to map List<Role> to List<RoleModel>

Solution

For flattering I was using configuration from the samples in Emit Mapper source files: http://emitmapper.codeplex.com/SourceControl/changeset/view/69894#1192663
To make the names to match in Company class should be the field with the name Id

For mapping List<Role> to List<RoleModel> I was using custom converter:

public class EntityListToModelListConverter<TEntity, TModel>
{
    public List<TModel> Convert(IList<TEntity> from, object state)
    {
        if (from == null)
            return null;

        var models = new List<TModel>();
        var mapper = ObjectMapperManager.DefaultInstance.GetMapper<TEntity, TModel>();

        for (int i = 0; i < from.Count(); i++)
        {
            models.Add(mapper.Map(from.ElementAt(i)));
        }

        return models;
    }
}

So all together:

 var userMapper = ObjectMapperManager.DefaultInstance.GetMapper<User, UserModel>( 
             new FlatteringConfig().ConvertGeneric(typeof(IList<>), typeof(IList<>), 
             new DefaultCustomConverterProvider(typeof(EntityListToModelListConverter<,>))));

There is a problem, using Flatterning Configuration with Custom converters, check my question: Emit Mapper Flattering with Custom Converters
