Hello guys,

I'm just wondering does anyone know any source, method or specific way to write an official thematic letter or propose/offer to a company. Last night an unique domain ideas came in my head about very well-known global company. I am not sure is this the right way:
1 . First, I must register those names(best tips where);
2. Then I must send the letter to the company;
and third ... must pray this company to buy my domains.

If you think that this is not the proper and teasy way, please show me how to complete the task.
Thank you for your time!

Best regards.
