Dear Sir or Madam,
I would like to know more details about your proposal, (working hours, meetings, requirements, and other things)
If you want we can make a call so you can tell me more about your project. There I also explain you what could be done, how my work is, and then I can make a plan. Do you agree?
If you agree, tell me what time are you available. I am always free after 17:00 (Uruguay time)
Regards,
Francisco Shaban
