Greetings,
I have read Project Description & understand the initial high level requirements, as you have nicely explained the overall business domain but we still need more detailed requirements or high level list of features.
You also mentioned about the possible website, so if you want, Website, Back-end, iPhone App and Android App, then I am afraid that US $3,000 is very low budget, I mean in this website, even only website is not possible. So, please let me know, if you are flexible in your budget, we can then discuss further to move forward.
Please drop me a message thru' PMB to start further discussion about your project, as we cannot write much on this initial message bard due to limitation of characters.
Our current bid is just a placeholder since Freelancer requires to submit the proposal but once you respond us, we can then finalize it.
Please check out our Freelancer profile https://www.freelancer.com/u/leadconcept.html, as we have delivered many successfully projects lately and let me know, if you want to see some of our recently developed projects.
Look forward to hearing from you and talking to you further thru' Freelancer private message board.
Regards,
YK
