I also do not have the experience you require but can empathise with the fly tipping/littering/dumping issue. One had a load of dug up tar dumped behind my back gate. Funnily enough just down the road a household were extending all over including replacing the pavement in front and adding the dropped kerb. Not that it was them of course. I had to get help and make umpteen trips to the dump myself. I could tell you exactly how I felt at the time and how depressing it all was but I suspect the post would be deleted.
What I can say is if you can not afford a lot, which presumably rules out a professional fitting, then DIY and something from, say, Maplins, might be an option for you ? It's where I'd start looking.
