LF Herbie Plumbing Help

[input80]

Hi, I am not sure if this would be the right place to post this request ? I would like some help this weekend to convert my corner overflow (2 holes drilled: durso & return) into a herbie. I need the physical help from someone that has knowledge & experience in this area, as my skills are extremely limited. After reading extensively on this matter, it seems that a ball valve can be used (with some fine tuning difficulty) as opposed to "must use a gate valve" ? I would also prefer to use clear vinyl hose wherever possible, I like the see through look.
Please pm me with your time availability & what you would charge.
