Hello,
I would like to offer myself as your designer for this logo job. Please, take a look at my portfolio here at Freelancer, to see some of my previous designs. I'm a professional, so you can expect pro result.
At this point I can suggest that if you want to use your logo (to convert it to vector), you don't need that lower part of it. There are too may details/objects you don't need. I that two part fence mean "cut" it can be simply be done in word "cut" to slice it in two and slightly mismatch position of upper and lower part.
But if you want totally new logo, that is whole new job to consider: how many colors, simple or complex, modern or classic, font selection. I can't just throw sample just on those 4 bullets. I mean, I can, but new logo can be miles away from what you want...
If you just want converting your logo to vector, bid will be 50$
Regards,
Arsen
