It will cost you $30 to do this on rentacoder, if you are going to need so much thought for a small decision like this, how long will you require for the big decisions?
Just do it and learn for yourself if it works for you or not. What worked for random_yc_user_99 may not work for you.
I'm really confused as the hostility here. It's a pretty reasonable question, and there really is a difference between the different entities doing this type of service. Sure, it's a good skill to have, but it's rather menial work in my opinion. I definitely don't like doing it, especially the browser comparability stuff.
Well, I've got a bunch of pages so it will be a little bit more than $30. And I'd prefer to not have to get it redone multiple times because the quality of the work sucked.
Sure, what worked for random_yc_user_99 might not work for me, but it is also possible it will work great. And starting with some a recommendation for a service (particularly if there is any kind of consensus about who is good/bad) is better than starting with nothing.
