know about exchange, but they mostly all want sites for 1500 rubles with unique design, etc.
Welcome to the real world.
There is a small portfolio, experience in creating websites there are some.
First create a good portfolio at the same time improve their skills. Rich and full-bodied portfolio is always good. Customers will immediately see that you have "experience". It is desirable that the work was challenging, beautiful, useful.
After portfolio, improve your experience, as it can be. You must understand that there are such tasks that are not going to Google it just like that, although it is considered that it is possible to Google, but it is not. Sometimes quite complex tasks.
After you have a good portfolio and extensive experience, can take orders. Try to take orders for 100K don't do it. Stupid not master, because there is usually a lot of requirements. Start from scratch and eventually will rise to the normal earnings. All the time. And all those tales that knowing HTML/CSS and a little JS, you can hack a million in a month and relax on the beach sipping cocktails is complete nonsense.
Many people go years to good earnings, and not everyone goes. It first glance it seems easy, but when you get a bunch of inadequate customers will be bad. You need to set boundaries and to have pride. And always to work for food is not necessary.
Customers can search among friends, acquaintances, loved ones, and so on. Can walk on different forums, sites, offer your services. Order the is. In short, don't give up, no matter how difficult it was not. And maybe one day you'll get lucky.
