Help with switching from weebly to wp

Hi,

I am somewhat new to wordpress. I built my site using Weebly but it is hosted by Stablehost. I’ve had it for about a year now <www.dealtechpc.net> I would like to start using wordpress since it is more professional and has more SEO advantages, I believe. I don’t really care if my content transfers perfectly, I am willing to put hours and start over. I installed WP under my host using softaculous but when I go to the /wp-admin it gives me a 404 error. How do I move away from weebly?

Any input is strongly appreciated!

Liz
