What format are you planning to use; 120, 35mm, sheets? If it's 120 or 35mm, I'd suggest Ilford XP2. It's developed in the C41 (color negative) process so practically every lab can do it. It also scans easily and allows the scanner to use ICE for dust removal. That saves you a lot of hassle with cloning out dust in post. If you'd ever decide to do some darkroom printing, it prints well as it doesn't have an orange mask. My experience with XP2 was that I got the best results when exposed at 200 ISO.
On the other hand, as MartinN said, developing is not difficult and it gives you much more control over the end result. Kodak and Ilford films are of high quality and widely available. So if you decide to go that route, start with something that is easy to get in your area and develop it in the recommended developer of the same manufacturer. Liquid concentrate works easier than powder that you need to mix first yourself. Personally I use Ilford Delta 100 and 400 in 120 rolfilm, developed in Ilford DD-X. That works for me. I can buy it all at a local store, the developer keeps well and the film/dev combination gives me good results. I still print in the darkroom and (DSLR) negative scans are just for the web. I also use the scans for the catalogue and to determine what/how to print in the darkroom sessions.
