if you really want to attract investors/partners you'll need more than just using paypal and basic gmail. what i read is someone who cant do anything, paypal business is a simple process but you make it sound complex and also why paypal? there is clearly a better way to handle international money even a basic business bank is better than paypal.
i highly suggest a domain and email, a professional would like to see effort put into the project not ideas. Domain name cost $12/year so it shouldent but too much money and you can get free professional email with Zoho. Inside the website add stuff about you, your 33 years of game experience and ways to contact you
With all that you may get someone to donate some money, if you looking for an investor you may want to reveal your project, trust is something they like to see not some mystery game that may be a clone of another game.
