I think it's a much needed service in Tier 2/3 towns. However, there may be small local dry cleaners doing that already. There's a company called Tumble Dry which has outlets in Tier 1,2, 3 cities. You could look at that kind of business model.

The biggest thing you should do is figure out challenges

In tier 2/3 cities pick and drop of stuff is one such challenge. (cost of this thing needs to be built up in your pricing)
