In terms of advisory board members --- most will do it without being compensated...it all depends if they feel your business is in area that they have a lot of interest in and the knowledge gained from it will also benefit them personally and in their own business. Some may want some stock options, but the savvy ones know also that there is a IRS tax consequence to receiving stock options.
In terms of consultants -- these are usually expensive people. Most will want to work for cash. Some will take cash plus equity but only a rare one that will take equity alone. Incidentally, there are alternatives to consultants by way of using the same business templates they do. We offer many of those templates on our websites...please contact us for more info...this is a very inexpensive solution that has worked very well for most people. In addition, the templates will also save you time before needing to make full-time hiring decisions.
