This freelancer work is mind blowing. He produced top quality. He did a good job. He moved my footer off my old web site onto www.eternityready.com, his eye for detail is stellar. His work is top notch. He is reliable. He is honest. He works very hard. I highly recommend him for wordpress work. This guy is the man for your company. You have to hire him. He is so good at his job. I am happy with the results. It was little better than expected. The new footer looks just like my old one.

For a quite complicated issue, Andrzej succeeded in sorting one of the problems. He took the time to test and try to fix the issue and has good communication skills. The other one was a bit of a hassle but, in the end, the site works ok.
