The salary range you mentioned can be attained by working in an international advertising agency or some graphic design companies.
Of course, salary range is a negotation process between yourself and the employer. If the employer decides to start you from 2.5-3k, you could always ask why to understand their point of view for doing so. Unless you either have an ego or are already an established designer, then you negotiate a starting range from what you aimed.
I hope this information helps.
As for the quotation, I personally find these kind of "how much would a website like this cost" situation not very helpful - especially when there's a login. Because it may show the client is too lazy to draft a proper brief.
Anyway.. 1 topic we've always discussed in this forum is the price. There isn't a fixed price.
What I've always shared here is you'll have to find your estimate hourly rate. The calculation is based on your:
CODE
costs รท average time spent per project
For example.. costs = 1500, average time per project = 30 hours.. estimated hourly rate = 50
When you have an hourly rate, for any project which comes in, you gauge the amount of time you may need and use the hourly rate to give you an indication of price range.
Even if you're using a template and free modules, you would still use time to research, setup, configure and deploy. Time is money.

Here are some other quick tips for you about the industry here:
1: There will always be someone cheaper.You decide whether you want to work with the client.
2: Always ask for a deposit.There have been many cases shared here where client requests for mockup(s) and not award the project to the person who've put in the effort.
3: Always practice B&W - agreementsAlso, there have been many cases where client terminates halfway (for whatever reason), then decides to not pay for the work because they believe freelancers won't go to the trouble of seeking legal advice.
4: Never be misled by promises.Some clients will sweet talk designers with "long term", "refer you clients" and etc. If they're really committed to what they say, put it in an agreement like #3.
Well, best of luck to you and happy holidays.

Hello, nice to meet you and thx for reply. Yes I like here because here is more relaxing and very nice food too. Gained much weight

I wish I could earn 3.5k to 4k per month for now. And yes, working in a company will kill most of my time. So I wish I could find more ways to get more freelance job. Or even any ideas that could earn money such as selling stuff.
And just now, I got a project which need me to give them quotation. Could you please tell me how much should I quote in Malaysia if I will build something like this one but exclude the forum and blog parts :
http://www.menclub.hk/Is there any design group or studio that I could join?
Thanks
