It's awesome you wanna scanlate, but you should pick up a series that no one is currently working on. LunaaSnow is currently working on this. If you look at earlier chapters you can see how long ago it was updated. It's best to go for a seriers that has been abbandonned for 3 months+, or go for something that doesn't have a translation yet. That way, you'll be able to advertise for help (typesetting, cleaning, ect.,) and people will be glad to do so.
Here's a beginner Scanlating guide to help you start off:
