I'm with Bryster on this as an entry level thing the more good will you generate by allowing 'what you can afford' type of thing will surely get more business and possible recommendations to others...congrats on the foot in the door, and as an afterthought I might use their offer as a starting point if it's way too low and then just haggle a wee bit...a sticky quandry I'd love to have...LOL.. ...

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
