looking for some advice, guidance

I am looking for some advice, guidance, and help whilst I set up a CMS using google sheets, docs, calendar, app scripts. I have been plugging away and using info found online and adapting it, but now feel this is taking up too much of my time with not enough results. I have a good idea of what I need, but I do understand that there may be more that I am missing. Data entry form - New Client Data entry form - Items List Data entry form - Job Quote Data Lookup - Overview of above Data Entries, + consolidated sets of data (ie FirstName, LastName,Address1, Address2, Address3) Document Generation - Home Survey Notes, Quote, Invoice, Receipt, Job Sheet Calendar entry - Survey Booking, Collection Date, Delivery Date, Payment Dates. getUUID + Create Client, document and job IDs I believe i have everything ready for the scripts Lots of ranges, forms, and templates, views are set up. and some scripts started, but I think its time to call in a pro! how can you assist with this project? I appreciate that there will be costs per script etc, so I set a rough price of £444.00 Some scripts are build but not working as expectd. Most document templates are ready to go eg. {{FindReplace}} Must be able to prove registered to work self-employed in the UK. A longterm project with lots of parts, exact tasks will be discussed further
