Hello! I want to write a message to someone on whatsapp (just a reminder in a professional way)I will start working with him as a freelancer. we have already conversation over phone. Now I want to send him a short reminder. so can i write him.
Hello! You seems very busy and i hope it didn't bother you. I'm waiting for your response. Actaully I want to start work with you from tomorrow.
What you have written is understandable. However I think I'd be a little less abrupt. They will already know they've not responded so maybe say, "I'm hoping to start work on the project tomorrow. Could you confirm to me later today that you have agreed to use my services, so I may start ? Thank you."
You seem rather busy so I hope this message doesn't take up too much of your time. I am still waiting for your response regarding *"insert What it is regarding here"*. I am eager to start working with you as soon as possible, tomorrow would be good for me.
