I really appreciate for the ground work you have done for your business and i will greatly recommend you to go ahead if you believe in your idea, it will work wonders ..trust me..
well about your design issues, i'm entrepreneur from india and deal in website designing,
may be you can out source some of your work to me .. without disclosing your exact idea.
this gives you two benefits:
1. cost is the very obvious one,
2. you can be relieved of this load so that you can focus on other aspects of your business.
Do let me knkow if i can be of some help ..
