You shouldn't expect much for $2500. That wouldn't pay the salary of a low level marketing person for a month. And that wouldn't include expenses and benefits. For $2500 you can get an okay DIY package that may take you several months to learn.
I charge many of my customers a minimum of $5000 per month plus from 12 - 25% new revenue for a limited time tied to what we bring in. A real marketer is not going to work for free. And in marketing you get what you pay for because great marketers know what they are worth and don't waste their time with low ballers.
