Many people may not select the appropriate time for sending a proposal for the project. In that case, I would say, from 2pm to 5pm and from 3pm to overnight you can send the proposal for the project. The rest of the time is our day. At that time, the project was much later than Asian countries. If you want to take projects from a good country.Such as Denmark, Sweden, the Netherlands, America and so on. However, according to their time when the afternoon, evening and morning and night. At that time, you have to choose whether it is night or day in our country.
Nevertheless, I would say that you will send proposals at night. At least every day during the day, try to send a proposal as soon as you get a project. Then it is possible to get the project very good.
