customized costume and graphic t-shirt inquiry

[chessimprov 0]

Hi all.

I'm looking for someone who can make a full body customized costume and/or a graphic t-shirt.
I am near the Philly area.

Any recommendations who I can reach out to ?

Thank you.

I'm now also looking for a canvas graphic design maker (backup).  I have a contact, but I'm not sure if that person will be able to get back to me anymore.

Canvas maker was in contact with me later on and canvases now obtained.

I finally found a person who seems willing to do my customized costume of Klaymen from the Neverhood.
I'm not sure what kind of things I should look for in the contract.

The designer mentions a company name, but is there some kind of business certificate or such I can and should be asking for?

He expects to have the costume finished in 6 months.  I can wait 1 full year.  Maybe a refund clause minus $50 or $100 that I could request my money back if the costume if not finished by then?
I'm not sure about materials or what works for comfortability.
 

 He has certain details such as:

Eva foam that will be sealed and than painted with acrylic to look like clay. 
Fans will be installed in the head for cooling purposes. 
Clothing worn by the character will be hand sewn and included in the commission price

Any thoughts on what should be added and/or asked?  
Thank you.
