Thank you for taking the WordPress Assessment Test.
You most likely would benefit from a professional firm. I don't focus sites you might be looking for, but I can recommend many companies out there.
Yes, you still could attempt to build a site yourself. But really who are you kidding. You don't have time and you have a budget for it.
Here are some recommendations for web development firms.
Some of the links in all posts may be affiliate links, which means I may get a commission if you end up purchasing their product or service. You will never pay more by using my link compared to what you would pay if you went directly to their website; in fact you may receive an exclusive discount. And it helps me keep the site running!
