The cost of this varies depending on what's your current state and requirements, the Price I'm giving you is a rough estimate, certainly you can get things donde with $300-$400, but please consider for example things like:
Do you already have a hosting service? Do you have your own domain? Do you need paypal integration
Do you already have logos, banners, slogan, fonts, colors, etc?
Is this foa single Exchange rate (USD) or you won't need on-line payments?
Do you need social media integration?
Are you interested on providing cuopons?
Do you need events management or calendar fucntionality?
Will you able to support the site or you'll need help on periodically updating content (how often)
If you answer most of these questions, I can provide a more realistic proposal. And as advice, before accepting any bid, ask all of these type of questions yourself to the participants.
BTW, not sure where you are located, but let me tell you that my team is located in Mexico, we offer wing-to-wing solutions and in case of the States and Europe, we offer services alinged to these timezones, which is important when you need support
BTW: For these type of requirements we use Joomla, K2 and VirtueMart integration
Once I have more information from your side, I can give you the outline and plan you'll certainly need
