My point with the rupees vs dollars wasn't that you're using the "wrong" currency. There's nothing wrong with stating your prices in rupees.
It is pretty obvious that your target market is India and people used to the idea of dealing in south Asia -- and that's a great way to get enough initial clients to build an online portfolio of "live" examples of your work. (I would make sure that part of the agreement always allows you to link to the client site when you deal with a business, or at least that you can use screen shots on your own site.) If you can live on the income you get at those rates (it would be impossible to do that here in North America), you should be able to get a lot of work -- and in doing that, you will also build a toolkit (macros for your graphics programs, snippets of code, HTML boilerplate, CSS/LESS/SASS skeletons, and so on) that will allow you to work more quickly and more effectively. And that toolkit will make you more valuable, since you'll be able to translate your design ideas into reality a lot faster. (The actual design ideas should be the hard part.)
There are almost 50Rs to the dollar these days, so if you double the numbers and use dollars instead of rupees, you would be charging almost 100 times as much as you are now. And on the international market, that would still make you "cheap".* Cheap enough, in fact, that people would be suspicious of the quality they can expect -- but with a solid portfolio of real, live sites available for viewing, you can cut through the prejudices around outsourcing.† It won't be something you can do right away (that price would put you out of much of your local market) but it's certainly something to consider for the future.

* A typical professional designer in western Europe or North America would charge at least ten times as much.
† It's not all about racial prejudice. There's a sort of "factory mentality" in many of the large outsourcing IT-related companies in India that discourages good practices and developer improvement. And to be completely honest, the schools are competing based on the number of people they can graduate rather than on the quality of their education, so there are a lot of people with computer science degrees who shouldn't be allowed anywhere near a computer (even to check their own email). I've worked with some marvelous small and independent Indian contractors, but my experiences with larger companies have never been good.
