Currently, I'm of the opinion to just make do with the photos you have. With this collection of photos, I know that they were not properly cared for through the years. Many of the photos have a pinkish halo around the subject of the photo (me) that provide great challenges to retouching these images. I could pay to have someone re-work the images, but I can assess that the work would be challenging. Thus, I decided to just use the photos I have and use a neutral, non-busy scrapbook design.
There are several reasons I decided to let the photos be, beyond the financial aspects. The strongest reason is that the strange coloration is telling of the time period when these portraits were taken.
Honestly, the decision to hire a professional when a retouch is beyond your skill set is your call. Just know all is not lost if the photos aren't as 'ideal' as you'd like them to be.
