Sure Eni. It is going to work well. A taxi exclusively for ladies is a very rare service. This is a niche venture. Start creating your social media profile so that you can get organic reach till the time your venture is launched. Do create a web profile about your venture, so that people would visit your website regularly for any transport requirement. Gradually, you can organize an exclusive holiday tour for ladies and working mothers and I am sure it's going to be a great fun.

I would advise that you do research in your target area and audience. You have to determine if there a is a need, what, if any competition is out there and your strategy for getting your target audience to see the need.
