Lightroom has a whole lot of presets, including ones for B&W processing and color processing.
Since you are new at this, I'd set your expectations low, as in you are "learning", not being a professional retoucher.
And then, play with those presets and get a feel of what "works" in Lightroom! That's a great "starting point", since you can freely move around from preset to preset (although you may need to click the Reset button in case one preset has an "additive" effect to the previous one).
From there, the "world" can open up as you move on to Photoshop and more complex but powerful techniques. Whether you are ready to tackle PS for this one "job" is, well, up to you and the time constraints you have. You can, for example, look up "cross-processing" for some interesting effects (retaining and "tweaking" the colors and contrast and such)...if you have the time to pursue some online tutorials!
