Please gimme advice

Hello all
I didnt know into which thread to post this message.
If I posted in the wrong one please move it in the right thread.
I am a dentistry student, and want to make a website on the teeth treatment problems and teeth implants.

I wrote several articles for this theme, installed the wordpress engine, but I dont like what I see in the result.
Could you recommend me a designer who could improve the look of my website and how much it would cost me.

Here is an example of my website [link widoczny dla zalogowanych]
Thank you in advance. Here is the contact email [link widoczny dla zalogowanych]
