Oh, Neil, even I am a man, I have to admit I like you more after reading such a piece of advice. The danger of your advice is propotional to the trust you place on ladies and purity of your heart. Obviously it is revealed from your so huge eagerness to get to real communication with them ASAP. So you see, even you were to eat the apple if you followed your way, you are still as pure in heart as Adam. Far opposite to David's view, I believe an innocent and naive heart is a perfect start for a successful relationship.
Most agencies, I believe, will not dare to accept such a term. The reason is simple, they are far less innocent and naive than you are. Most translator will regard it a hook and believe if they do bite the bate, severer complaint to chnlove with vital evidence will end their career and perhaps the agency's.
Then let's come to your intention. Will it really help to realise your intention if they accept such a deal? Let me explain it this way. The more attractive the lady is, the more EMFs her account receives. Usually she will choose one or two (seldom more, in an extreme case which I know, the lady chose seven, well, a really energetic lady, I admit) candidates whom she is interested in to communicate with herself or periodically supervise the communication. The rest, if there are any, are innocent lambs for translators to deal with, whom the lady usually has no knowledge of or cares not. If you unfortunately fall into that flock, a fee to get access to the lady will not help to promote your place in the candidate list. And if you are the lucky ones, the money you pay for EMFs is a good sign of your generosity to spare her the trouble and hardship of dealing with translation herself.
Finally but formost, although it is a cruel world. Sometimes even the mere pursuit to survive, not to say thrive, presents us difficult choices to make between dignity and prosperity. I still firmly believe it is better to play clean and lose than to play dirty and win. Let's help the agencies to be clean, shall we?
