Need Orchestral Score/Parts

Does anyone have the orchestral score and parts to the Joseph Martin cantata, “The Song Everlasting” (Harold Flammer, 2011, Stock #HL 35028094).  We will be doing this work at Opportunity Presbyterian Church on April 17, with rehearsals beginning next week.  This work actually comes with two different oirchestrations – one for full orchestra, the other for small ensemble).  I mainly want to see if the scores are interchangeable.  I’d like ti perforn the work using the small ensemble accompaniment, but with additional strings.  Anyway, if you have the score, I’d love to see it.  Also, if you have score and parts and we can use them, I would be happy to rent them and cover cost of shipping both ways.  Flammer has both instrumental accompaniments on data CD’s, and having those would be the best of all!
