Hi Laura,
You might want to try elance, http://www.elance.com.
You can sign up as a provider and perform various services for people.
I use elance all the time for various tasks, mostly business/administrative tasks. However, I did find an LA on elance that does all of my color rendering, perspective drawings,etc. He can also do drafting work for me.
I did not see many LA’s on elance (aside from my guy), but there are numerous providers that offer civil engineering and architectural services.
Check it out, it’s a very cool service. Let me know if you have any questions about it.
Good luck to you!
