It seems that you have two options, First option, can you provide what the client is asking without risking the product? If so go in the meeting prepared with a project proposial and negotiate your price. But if this is something too much to do and will eventually harm the product since you said it its a two person team, then its probably best to let them know that you cannot offer that service but be ready to offer them some advice/recommendation, for example if you have a company in mind that could do the job.
