I agreed with suggestion of using a prepaid phone - and buy it with cash in a store outside your area code, with no cameras recording who buys. Most services allow you to buy cards for extra minutes for cash just about anywhere. Buy 2 phones, use one number for advertisements, posting, etc, the second for established, verified or previously seen clients...every 6 months or so, throw out the first and get a new one.
Don't store any client info, even tel #'s in your phone or on a PC - better to get an anonymous website through a service like hotmail, store your records online and don't write your user name/password down anywhere - that way if somebody takes/searches your PC/tel/records,nothing is there to be found.
domains - there are many services that offer private registration - it is worth it, never use your real name, tel #, and best thing-use aninternational registrar outside the US. Don't use your domain registrar for hosting.
website - use a service outside the US, different from your registrar; most services give you multiple, if not unlimited emails, use them- one for ads, posting (that you change periodically), another for establish customers. Check email via webbased access, not download to your pc. Set your browser/email to block images - people can place an image on their server, include a hyperlink to it in a html email, then when you view it, it "retrieves" it from their server and sends to your location, giving away the IP address of where you are located (which, if someone wants to go to the effort, can let them contact the service that owns thatIP, check their logs and trace who it was assigned to on any given date/time, and where they were when they accessed the internet.
Having a legitimate job is a great plus, but rather than something that requires a license, I'd suggest something like "marketing consultant"
For finances, have several accounts, make cash deposits on a rotating basis, never too large (not above 3-4K avoid attention). Make deposits at a busy branch, during the busy time of the day - you'll atttract less attention that way; better yet,use the drive through window so there are always many cars lined up behind you and they want to take care of you and move on quickly. Don't live a visible lifestyle above your tax reported income - that's an obvious way to attract IRS attention - and they can be the toughest creditor to avoid/dodge. If you don't report all income, at least report all that you deposit anywhere; save unreported amounts in cash for routine expenditures.
