Basically, you want to develop website for scheduling emails to send different user groups but can you please confirm, if you have more detailed specs or you only want to develop these features, which are mentioned in the project description?
Honestly speaking, there are no technical hurdles or issues. However, our team estimate is coming higher than US $750, as this is low budget, so would you be flexible in it? No doubt you can get lot of bids within this budget range, as every bidder want to get this project, because on this website, whatever budget you will select to post the project, mostly people will bid within that budget range, no matter what actual working hours or cost it takes to develop. So, if you're flexible in your budget, we can surely talk about it more in detail, if not, then I totally understand and I wish you good luck.
You may ignore the bid & once requirements are finalized, I will then give you firm bid.
Look forward to hearing from you & start further discussion thru' private chat.
Regards,
YK
