I think its totally depends on the work quality and offcourse your location too. If you are European company then I think your price are competitive, as the operating cost in those coutries are high and services are quality. Freelancer from Asian countries like India, Pakistan, Bangladesh are comparatibely cheaper as their operating cost of very low.. Overall, I won't consider your prices as higher, if you are providing quality services!

I think it's totally depends on what kind of work you suppose to share and how much will you pay? Secondly, how much work load do you have. It is not that easy to ask this question with limited information. If you seriously wanted someone to join you then discuss all the aspects openly.

It depends what level of expertise or skills your required. If you are beginner then you should go for CSS, HTML, JS as these are basics of web development. For the next level JQuery, PHP and MySQL are important. W3Schools and Codecademy are good platform to learn. I also recommend you to learn about Responsive Web Design, as RWD provides optimal viewing experience in all types of devices such as Desktops, Tablets and Mobile Phones. Here is a good example of responsive b2b trade directory. Cheers

What kind of website do you have? If your website is related to shopping then I suggest you to try Magento or Joomla. Responsive Web Design really makes the life easier, recently I experienced converting a b2b trade portal on RWD and experiencing good results so far.
