How to get investment for your profitable project and convince the investor?

The one should be understandable and helping minded guy.

Do u mean : How to get investment for my profitable project and to convince the investor?

I am sorry, first, you have to brush up on your english. As for your project you have to submit a proposal, the best is in powerpoint slides indicating the type of project, the cost, the benefits, the demand etc.

No one invest in a project because he is understanding or help-minded. A sharp investor will recognise the benefit of the proposal and the money he can earn from investing.
It is not depending on whether you think it is a profitable project or not, it really depends on how your project can fit into the market condition and whether there will be a demand for it.

You will need to do a business plan or a project paper first to convince your investor that it is profitable for him . Your plan must be able to show the kind of products or services that you offer. Next ,who are your potential customers or target market.
Do you have an edge over your competitors? Is your product new and unique in the market. Who are or will be part of your management team. You will need to show a financial plan as to how you are going to make it profitable for the investor from the preparation of a projected Profit and Loss statement, cashflow statement, and also a Balance sheet. A lot of forecasting will be required based on actual figures if your biz is already ongoing. This is a basic requirement for anyone requiring a loan from a bank or private investors, as most investors would like to know the kind of risk they are willing to take in your biz, and the kind of return they can get if they invest. You can make a search for help with your project paper .Many are available online. All the best
