Hi!
Please allow me to help you out with this one. I have 15 years of web experience, the last 5-6 of whom I have been working with PHP and Wordpress. That includes bug fixing, tweaking as well as building things from scratch.
I know exactly where to insert your various banner codes, and will provide excellent quality work and good communication. So, for the best value for your money, you know where to find me :)
Have a nice evening!
Best regards,
