Hire me on Freelancer.
$100 up front, and we will deliver you the design illustration including the website, and your mailchimp template. If you don't like it, or you want to go with someone else, you can end the contract there.
For this design illustration, I'd need a week to get you over something quality.
If you like the design illustration, then we'd ask for another $400 and $25 per month to cover the costs of hosting your website, security, and then also a direct line to me to get whatever you need on a timely basis.
There is a lot of value there, but I can't prove that to you until you allow it.
We'd facilitate this on Freelancer as this also allow you protection in the unlikely event that you'd want to raise a dispute etc. (aside from $25, this would just be a recurring payment you'd send to me via Paypal)
