In Need of An Update: Blog Edition

So I have been wanting to update my blog header...I just wish I could do it myself. :(  

I want to do the things I noted above.

So I am asking for your help...is this something you can do? 

How much does something like that cost? 

Even though I would like to....I don't think my husband would appreciate me adding blog design to the growing list of things I want to learn how to do!

If you can help, or know someone who can...please leave a comment! 

Thanks!
