you can use any bitcoin exchange and the money to your bank account, or if you don't want to use your bank account because you're afraid your banker see your "great income" get a bitcoin debt card, there are enough service offerring visa or mastercard card. no need to make things more difficult than they are
The work you say is not really feasible, it only works for those developing countries where the bitcoin support is. In my country, bitcoin is not universally recognized, so no bank accepts it. If we want to sell it, we have to deal directly with other people or use intermediary sites, however, those sites are not really secure. So, we choose direct deals for large deals.
