I am a purchasing agent for foreign companies. My clients find me on the Internet. I provide services so my clients pay me my service charge. They don't personally know me before they contact me. I met quite a lot of businessmen. They disappeared after they got what information they needed so I end up empty-handed. Some businessmen even told me in email,"OK, regarding your payment, I will wire the money to you tomorrow." After a few days, no email from him and no payment arrived, when I sent an email to ask what was happening, the businessman became unresponsive as if he was dead. Of course I don't mean all businessmen. Some businessmen are really good. Later I always request a upfront payment before I formally start to work on a project. However, a new problem arises. Some businessmen don't accept this request because they claim that they don't know me. It is true that they don't know me before they contact me. I suggest that I could provide testimonials from my previous clients, but it seems that quite a lot of businessmen are not interested in seeing testimonials. Then we reach a stalemate. How to solve this problem? Do you have any ideas?
If I take a non-payer up in court, it will cost me a lot of money and time and I don't think it is worth doing it. My service charges are not too much.
