Should a website cost $2,000 to build?

[Kim]

I want to sell several products. According to this website it'll cost me a lot of money.

I have checked:

Basic Word Press type website
No unique graphics
Contact forms
Simple cart shopping
Credit Card Processing
Paypal
Database reports
Traffic Statistic Reports
Search Engine submissions
Press release submissions
Twitter Integration
Facebook page

Here's what I'd like for my website. I'd like it to sell 5-10 different products. I'm going to have on-going contests/sweepstakes promotions to promote sales. Those are the two main goals of the website, every thing else on it would be used to support them. The contests require that I have the option for contact forms to inform people who win, and some basic control of other means to enter the contest on the website. I figure this means I will need some kind of database reports.

Is there any expenses that I have forgotten to add, or that are unnecessary?

This will apparently cost $1700-$2300. Is this accurate?
I'd like to include a lot of other functions, but it gets too expensive.

Also, are these one-time costs? I'm assuming I'll pay this once, plus maybe $100 a month tops to maintain it, and a percentage of sales to paypal/credit transactions that depend on what my sales are.

Is this accurate?
Isn't the 2k for labour...? 0.o
