This project left me perplexed. All in all, it looked like a project to integrate two e-currencies into custom script. The client, however, had no merchant account neither in WebMoney, nor in Yandex.Money (and is ineligible for Y.M.). There were a number of two-to-three day breaks in communication. On the whole, he's a good client, lack of outsorcing experience is not a sin. Developers - be warned. DO verify project prerequisites before you accept, DO plan some extra time for the project.
