Hi. Firstly, good luck with your venture, I hope you get up and going successfully.
I wonder though, if you’re not being very optimistic in your forecast of gross weekly earnings of £3k, on a fuel bill of IRO £800.?
That kind of work is very hard to find, and as I assume you will be working as a sub contractor, I doubt those figures are achievable. If you can do 3k on 1k of fuel, you’ll be doing very well indeed, but I’d be inclined to think that your fuel bill won’t be under £1200pw at best.
Let us know how you get on, but if you do find a pot of gold, don’t tell a soul.
All the best.
