The question is what the requirements are. Just some cutting, or actual video editing: compositing, color corrections, masking, font overlays, chroma keying, resizing, resampling, de-noise, de-flicker …
For pure cutting you can take from Windows Movie Maker, VirtualDub, some FOSS Linux Tool up to AVID.
For video editing you can go from AVID, FinalCut, Lightworks, Premiere Pro, Aftereffects…
Lots of choises. I don´t know the feature list, but for semiprofessional use maybe the “light” version of Premiere however it is called might be a good choise.
Otherwise I´d go with Lightworks, it is as professional as it can get in free software.
In our studio we got AVID, Premiere Pro and Aftereffects, and all the cutting is done with AVID. It´s expensive, a behemoth but the kind of russian swiss army knife tank
We´re also thinking of switching over to Lightworks at some point, but only if it allows video cutting over the net, where the master footage remains on the server and the clients work with proxy files of the footage and on export it takes the master footage. AVID´s not so great there - there is a addon package do do it with AVID but you´ll get a bill with 5 digits not including the cents
Personally I´d say if it is a thing you´ll do repeatedly, get aware of your requirements and invest in good software. It will save you a lot of time and wrinkles and if you got a few gigs it should pay of quite fast.
Ah remember it… Adobe Premiere Elements. Just like Photoshop Elements. Be sure to check out what features are missing in comparison to the “big brother”.
However, there are several versions, also Premiere Elements Pro… They range from ~60USD to 120USD which I consider very cheap.
There are also Elements packages where you get Photoshop too.
And if the “light” version isn´t for you, you can rent Adobe software now… You got work for a month? Just rent a Premiere Pro and After Effects License for a month. I think thats a great service.
That all said, with the above listed weapons in my arsenal I´ve never used Blender for Video editing, but I think it will become one of Blenders strenghts with upcoming/ongoing Project: Mango. - you´re just too soon with your gig
