Hiring a consultant shouldn’t replace your own knowledge of your business plan.
If you have were able to partially write a business plan but lack some crucial elements, do you will need a consultant to greatly help finish it up? It’s an extremely tricky call, deciding which parts (if any) of your plan ought to be delegated to a consultant. When push involves shove, you will end up the main one running the business. If it is time to create the paychecks, your signature will be on those checks. When buying supplies, you are investing in payment. Even if you are not the individual who creates your financials from scratch, it’s essential that you realize them and understand the assumptions behind the numbers.
