Website help - SEO for newbie

[Ryan Dosenberry]

I built a basic website a few months ago using Squarespace but now I'm kicking myself I didn't use Lead Propeller or another company that specializes in this.  What I'm wondering is, should I hire someone to help me with SEO on my current site or start over with a company like lead propeller.   Cost will also play into my decision since I'm just starting out and looking for an affordable way to get my website at least generating some leads.  Right now my only traffic is from my direct mail campaigns.  

Any tips would be appreciated!
