Well Mike, being SE myself I can see what you are saying, but how much are you saving?, £100?, £200? spread over 50 weeks thats £4, per week (a 'happy' meal !), so £0.10 per hour. (overly simplistic sums I know, like me maybe you work 50 or more?)
Don't be in a race to the bottom. Sell yourself and and your skills, not a price.
Just a thought, and who knows who is reading this, all those luvverly potential customers who do actually value an end result more than just a price, they are out there, let them seek you out.
Best of british to you, squire.
