Know a lawyer that's done Retail sales agreements-WA mobile home?

[Dawn Young]

Hi all! 

We have purchased and done a light rehab on a manufactured home in a park.  We will be selling it on terms.  (payments)  According to my lawyer, since we do this as a "business", our contract with the buyer needs to be a "retail sales Agreement for mobile home". He's not done one before,(he mainly works for parks and they have different forms) and at $250/ hour it would run us $1500.  I could do that, but would rather not.  Anyone know a lawyer in WA that does these?  I'd rather just pay someone $400 to touch up a contract for me than to re-write it for $1500.  Hopefully I've made this clear, and understandable.  Thanks!!!
