what is the easiest way to send buyer requests very quickly?
There is no such a thing as “EASIEST WAY” if you need someone’s project you have to convince him/her for it so make a good message layout with your portfolio and ask them to contact you before starting the project.

If you want easy way that is copy/paste without reading the request. However, be ready to never get any reply from the customer because that way it will never get you any order
