What are my needs?

I'm gonna try to offer a service that I have yet to see in my area. I will be using my 5d MKII to shoot tours of homes starting from the front yard and going through the house and ending up in the back yard. Here are my questions:

1.Use vimeo or youtube?
2.Use background music or not?
3.Where do you get your music from?
4.What lens should I use? I have a 35mmL or 24-105mm L
5.If the above lenses don't work, money no issue, what should I get?

Here's my view on what you should get. I know my setup isn't up to par with what i'm saying since i'm still focused on getting into graduate school, but i'm going to be a partner with a friend who is starting a videography business here soon so i'm setting things up for myself as well.

1. Vimeo works better than youtube if you don't care for views. Also they don't have as strict audio censoring that youtube has if you plan on adding mainstream music.
Keep in mind that you can also get permission or licenses to use certain songs, but I find that to be a hassle if the song isn't that important unless you're making wedding videos.

2. Like I previously said, if you are using your own music then you should use youtube, if not i'd use vimeo but make sure your music is universal and not hardcore metal or something. Instrumental/classical is always the best.

3. Cd's, torrents, itunes, friends who produce beats, friends who want to get their music out. Your choice.

4. Use the 35mm if possible. A glide cam or stabilizer is a MUST when shooting your film unless you're planning to use a tripod for panning left and right around rooms. I advise you to also invest in a wide angle lens such as a Tokina 11-16mm or a Canon 10-22mm instead of using a zoom lens. It'll give you more field of view to work with and allow a better view for people who see your videos.

5. ^ some mentioned in this paragraph, however, you want to stick with primes such as much as possible. Another lens you can look into is the Sigma 30mm 1.4 but you already have a 35mmL

Summary, use Vimeo, use prime lenses for depth of field, use wide angle lenses for landscape panning, get a stabilizer shoulder rig or glide cam.

Good luck.
