Sean, uou are asking a lot here.  You need to back up a step or two so you can properly reply to these objections.   Such ask, do you know your competition,  the value they bring, their price, etc.  Do you know the company your talking to, their pain points, mission, etc.

If you do your research ahead of time this will reduce your time going forward with knowledge and confidence.   Generally two major factors that others look for when switching services or products.  

If you are more expensive than what their company is currently paying, ask yourself,  "what additional VALUE does your product bring to them?  

If you are having trouble getting past the gate keeper, then you did not do a good job building a relationship with that person.  Don't think that the person at the front desk isn't important because they could be a family member of the owner (decision maker). 

And your third, never just leave a business card!  It will get filed in the circular cabinet that is emptied weekly or sooner.  Have a brochure ready, a free gift for the gate keeper, or something similar. 

Hope this helps.
