you are right, but i don't know where to change prefix. I can only edit post content. So it should be WTB instead of WTS, sorry for this.
Hello Tigergb 1st change the title to WTB & are u sure anybody SEO expert provide u services in 20USD per month i think if u want quality services then riseup ur price man .......... bst of luck .......
If the domain is really new i would suggest you to decide your main keyword and start the first month just buying few PR2/3 backlinks (you should get them with $20)
