How to find customers for agency bookkeeping

I am also a salesman of a financial institution. Now most of the customer resources are advertised on the website by the company itself, such as 58, Fair. Baidu, 360 and sogou. When advertising on the website, most of them are charged according to the number of clicks. Whether anyone consults or not, the click fee ranges from a few dollars to more than twenty times. If you cooperate with the platform, the price is different. Most of them are charged according to the real amount of consulting customers, and each has its own advantages and disadvantages, depending on how you choose. If you are a salesman, it is better for the company to allocate customer resources to you. It's hard to find them yourself. It takes a little time to rely on friends to introduce, send business cards, advertise on the spot and add buttons. Most of the group are peers, with fewer customers, and the effect is not obvious.
