Ok, I'm a software developer, that's what I do for a living, I feel I haven't been getting much clients because my mode of marketing is poor.

Now am thinking of something new, since I develop banking software I wonna sell to micro finance banks, I'm thinking of printing out different letters with my own letter head and going about dropping it directly to the manager at his doorstep in his office.

First of all, there is an understanding that I'm not yet registered with central Bank here, but I'm thinking of starting somewhere as I have registered with CAC.

Is the mode I chose a good one? Dropping the proposals directly at the micro finance bank and waiting for who's gonna call? Because phone calls this days, they hardly take it kind of serious.

Help.. really need business advices here.
