Hello,
First of all; my bid is higher than your budget but please read my message and consider this.
I am a senior PHP developer. I have 10+ years PHP, CSS/HTML, JavaScript and MySQL experience. I also have 6+ years Blockchain and cryptocurrency experience. I've build a coin before (I can give you the details).
Building a currency is not simple thing. It is a complex system. Because of this I can build it for 800 USD within 10 days.
Please send me a message to discuss the project details.
Thank you.
