Dear Sir,
I have read your Project Description & checked the attached PPT file, so let me formally confirm you that we can do this project but since you want Website, iOS App & Android App, so this cannot be done in US $1,500, as it is very low budget.
So, please drop me a message thru' Freelancer PMB, if you're flexible in your budget. Just so you know, our current bid is just a placeholder to submit the proposal & start our communication.
Look forward to hearing from you.
Regards,
YK
