Most important place to start is to ensure that Business account is setup properly - part of the process is going through the hoops to "verifiy" your account.
You can verify your account by completing two out of three steps:
* Linking and confirming your bank account
* Verifying your credit or debit card information
* Providing your social security number.
Then start planning about your items - meaning you need to consider shipping methods, collecting sales tax, do you plan to sell global or just to locations in the US, etc. You can setup shipping and tax tables in your PayPal account.
Then there's your web site - does your ISP give you full control or are you planning to use what they offer, pre-made templates, etc.
Next, do you plan to have a shopping cart or just sell items individually. You can create the necessary Add-to-Cart or Buy Now code from within your PayPal account. Basically, you create the code, then copy and paste it in your web page. Note, some web site hosting services won't accept that code but, will accept text links - you need to know that stuff up front.
Bottom line - it takes a bit of planning in advance.
