Depends on the scope of the project.
Your best bet lies in one of two routes...
#1 Set out EXACTLY what you want the site to be able to do... make mock ups and write descriptions of every detail. THEN outsource the project on one of the many programming outsourcing sites where people bid for the job. (if I had to guess... shouldn't cost more than $5000)
#2 Find a capable programmer that you trust and partner with them... keeping your cost at ZERO (minus server costs which are almost nothing for a project like this)
