How can I find matching cabinetry and hardware?

Thanks everyone for your help. I went to ebay and did a quick search. I found a Jayco cabinet door that will fit perfectly. I don't know if mine is oak or pine, but at one time I saw that Manchester Oak was standard on my model, so I think I may have oak. The one on ebay looks like the same wood grain, but it says "pine". The stain appears to be different. Can you sand these cabinet doors down and apply the correct stain? Here's the ebay link:
