Here are some on the surface, nonsensical pay sales
payero.com $106
paytix.com $850
paydio.com $3,542
paydro.com $1,688
paydoo.com $145
Your domain probably closer to payero.com, AND harder to pigeon hole into something (more down).
Might be a person's name. I didn't follow that trail very much.

Could be paypeso without the o
Good Luck
